×* Added some scrolls in various rooms as notes to self that certain rooms could do with being moved or replaced.
* I must have been mad to use spiders in Palace style (or at all really) in AE. Looking back it makes things so much more annoying to deal with than it needs to be. Replaced all spiders in level 13 with roaches, except where it has comedy value.
* Level 2 1E: Better wording of challenge scroll
* Level 2 2E: minor changes
* Level 2 2E1N: major overhaul
* Level 4 3E: significant changes to prevent unintended solution
* Level 5 1S1W: Added extra floor tile to reduce efficiency requirement slightly
* Level 8 1S1W: Added helpful scroll about movement order of spawned roaches
* Level 9 2S: Added force arrows to fix unintended solution and massive sequence break!
* Level 13 2E: Made the challenge slightly easier by making it obvious a certain potion was unnecessary under challenge restrictions.

×*Level 4 1S3E: Flipped force arrow on Northern set of trapdoors.
* Level 4 1S4E: The same change to make it match 1S3E

×First Level: 1N:
Alternate challenge: Don't go to (8,4) [That may be an optimization challenge, thus not necessary.]

Second Level: 2E/1N2E:
I guess the easy way to do 2E is to enter from the south, clear the eastern side, and use the western passage. It is also possible to clear the room when entering from the west. In that case, however, you still need to clear the eastern side with 15 roaches a cycle. [I see these rooms were changed for the new version so the comments may not be relevant anymore.]

Third Level: 3W
Why is the northern entrance harder? There is a ready made alcove in the south for directing the queen out, which would have to be prepared when entering from the south.

Third Level: 1S3W
Interestingly, a failed plan which did not work as intended still allowed a solution. Had I solved 2S3W earlier, I would have just used the same pattern.

Third Level: 2S4W
As an AE hold, the checkpoint should be inside the NW section, even at the cost of a broken wall. Candidate locations would be the SE corner the the broken walls, or possibly one square west of the corner.

Third Level: 1S4W
Challenge: Extend the yellow door to (15,17) and add a challenge not to let the roach reach that square.

Fourth Level: 1S3E
It looks like the intended solution is to go around the loop almost four times, and then lure the roach backwards. However, there doesn't seem to be three paths going west along the north which leave a path going east for the roach. The other solution which solves the "secret" to the east of course also works. [Looks like it should be fixed for v3.]

Seventh Level: 2N1E
My first solution completed the challenge. I figured out the intended main solution afterwards. It looks natural in the puzzle that the entrance to the monster section close the doors holding the queens. The puzzle could then include a challenge involving waking all the eyes.

Seventh Level: 2N
Killed the serpent on spawning roaches. Other possible slots are the square where the queen originally is, and the north eastern alcove. Which way is intended?

Seventh Level: 1N1E
I could ALMOST build up enough distance on the trapdoors without closing a passage and forcing the eyes to backtrack. I finally realized forcing backtracking works, but I am still wondering if the other way is possible. I could reach a distance of 9, but 10 caused one of the roaches to turn around. I think I managed to reach this distance on the south side, so a mirror of this puzzle on the horizontal axis should be solvable while dropping all the trapdoors. A red door could prevent the solutions for this room working. I managed to solve this room while leaving the trapdoors in a state that they could be dropped if I could return to that area of the room after killing the monsters.

Eighth Level, Ninth Level, most of Tenth Level: played some time ago, but didn't write notes. Don't remember much specific.

Ninth Level: 2S1W
Solved challenge now when reviewing demos.

Ninth Level: 2S
Solution and exit don't require crossing blue door. Maybe add another roach behind the blue door? Or add blue door around existing roach? [Looks like fixed in v2.]

Eleventh Level: 2S1E
The difference is obvious enough here, that I don't know if the full spot the difference scroll in necessary.

Twelfth Level: 1S1W:
One mimic didn't do much, so maybe add a challenge to drop green door when placing mimic.

Twelfth Level: It is good that most of the rooms are small.

Thirteenth Level: 2E
Didn't solve this challenge. I can pull the spider to (20,20) before I need to take a third potion to become invisible. I can then either trap the spider on (21,22) or let it reach row 23. I don't see how I can escape the spider without using the southeast passage and stepping on trapdoors. I don't need the potion behind the trapdoors. Just the passage. (The non-trapping arrows on column 16 should be distinguished from the other arrows. Perhaps also mark the trapping arrows with trapdoors.)

×Level 2: 2E/1N2E
Seems better.

Level 4: 3E
My solution now is to hit one queen before the first spawn cycle. Is the difference that there are now no good squares for killing one roach a turn?

Level 4: 1S3E
My old demo is still valid, and I see the correct path in the top section, so I didn't bother solving it again. Is there a reason one of the orbs is a toggle orb? It doesn't add anything to the room.

Level 5: 1S1W
The extra floor is (8,10)? How about adding a yellow door to (25,14), which is also opened by the (22,17) orb. Add an additional orb which opens the door at (26,13) somewhere where it won't get in the way (for example, (16,17)). Then add a challenge to use that orb.

Level 13: 2E
Still can't figure out the challenge. I also can't tell what the difference is from the old version. (My solution uses 9 potions.)

Trying to think back to when I first built this room perhaps I thought the alcove was not useful for manipulating the roach? The Northern entrance is meant to be harder for two reasons, one, having the Roach leave to the North makes it easier to slot into its final position and two, the platform is not symmetrical, there is less space in the South, so harder to set things up while also leaving that way. I will probably remove those two extra trapdoors in the South to make the Southern edge totally flat as I have just resolved the room without them, but am interested as to why you think entering from the North is easier.

Both rooms require a similar pattern, but it can't be exactly identical due to the way you are forced to construct it with trapdoors or crumbly walls. It sounds like the rooms have enough flexibility in them to allow solutions that aren't totally strict, and that's OK by me.

Ah yes, good idea. I've moved the checkpoint for the next version to be after the trapdoors on a square that you're guaranteed to have to knock out anyway, so hopefully that will be better.

Hmmm... Well I just solved this challenge but it didn't feel to me like it made a solution all that different to the regular room, just slightly more efficient, so I don't think I'll go with this, but thanks for the suggestion.

I'm sorry, I really don't understand what you're trying to say here. I have no idea what you're doing here to solve the room where a challenging waking up all the eyes is harder. There must be some unintended solution I'm not able to spot. A demo would be very helpful here.

bbb wrote: Seventh Level: 2N

Ummm... there are lots of places to kill the snake here, such as where the evil eyes are and some of the checkpoints. Killing the snake is not supposed to be the challenge this room poses, so I don't really care how people kill the snake. I could add an obvious killing spot if you think that would be helpful, but the aim of the room is to use the snake to stop roach spawns from getting trapped while you run around hitting the orbs. Is that not what you did?

The aim of this room is to use the trapdoors to get lots of distance from the brained eyes so they unbrain and stop in the correct place when you hit the orb. I do that by building a small passage way then cutting them off at the last minute, did you manage something else?

I plan to do the spot the difference everywhere where the difference is only one or two minor changes, so even if it is obvious, it reinforces that that really is the only difference.

I won't provide comment so that I don't accidentally drop hints, unless you want any. But putting trapdoors under all trapping arrows is a good idea, thanks! Because you asked in another comment: the difference from the old version is that the potion near the entrance a few squares South of the one you must take first is now behind trapdoors, instead of only trapdoors in the corners of the room.

EDIT: Sadly, in AE itself, the force arrows in this style are red, making them extremely hard to see if I put trapdoors under them, so I will leave them as is.

If I am understanding this correctly this would simply trivialise the non-challenge room as you wouldn't need the snake at all?

×This is a really awesome hold, and will probably end up on my list of top favourites along with classics like Simon's Dungeon and Pickle Cellar. It's really impressive how you manage to keep coming up with clever tricks, linchpins and misdirections with such a limited selection of elements.

Level 1

1N: Right from the start, some tricky linchpin-hunting when this room looked like I had to enter from the north but couldn't get there, so I had to check whether I'd missed something in this room or another room. Nice trick

3N1W: We're doing movement order already? Probably a good idea, since later levels will need it, but this is one more reason why I would not recommend playing the hold in AE. Still, this is a good room, since the manipulation to get the roaches in line isn't trivial but can be worked out logically.

3N1E: Extremely devious! This was the last room I solved and looked impossible for a long time, because it makes you feel you are on a railroad and every move is forced, and it's not easy to spot the one place you can break the sequence.

Levels 2 and 3

It's a while since I played this, so nothing especially stands out at the moment. I don't agree with bbb about Level 3's challenge; this was a tough room, but the challenge is especially tough and requires a nice linchpin --


Level 4

2E: This is where I dead-ended on my first play session. An awesome puzzle with much more depth than you would expect, given the limited elements and tiny playing area.

3E: In spite of your reply to bbb, all entrances are still possible.

1N2E: This is a nicely constructed roach maze because it centres around one linchpin: that you can't get a roach back around the NW corner if you follow what looks like the most natural sequence, filling both SW force arrows first. Everything fell into place when I took it step by step and looked at what choices I actually had.

4E: This looked scary but wasn't difficult at all. Please put a checkpoint just before the trapdoor area.

1S3E: This looked absolutely horrifying, but was easily handled with a good strategy, namely looking for arrows going against the overall flow (and there are not many of these) and handling these one at a time.

1S2E: Very nice. The lack of force arrows at the room "exit" made the idea of starting from that side leap out, but it still wasn't trivial to manipulate both roaches at once.

Level 5

1N: This room really wasn't bad, not sure why you are considering replacing it? The solution only really requires the player to think about the 5-turn rule, not the N-E-S-W rule, and this rule is required for other rooms so it's good to get a simple starter room to help the player learn it.

1N1W: This, on the other hand, would probably be too difficult for new players, from memories of how much I struggled "pushing" an adder east in Dan's Dungeon. Then again, even though the hold introduces one element at a time and has a mini-tutorial on serpent rules, I don't think any part of it is really aimed at new players

2S2W: This was a really good secret -- it builds on the previous room in a very satisfying way, subverting expectations from the main linchpin of the previous room, and is still not trivial even when you've worked out its trick.

1E: A bit weird. I mostly lucked out in terms of getting the long serpent to go where I wanted it.

1S: A very nice room that looked impossible for a long time. I like the way that all four serpents are handled differently despite the fake symmetry.

1S1W: For some reason this had me stuck for ages; I didn't think of striking the orb again as soon as the serpent is through the doors to give myself more time. Once I did realise that linchpin, the solution was immediate; the extra floor tile isn't necessary and doesn't seem to help at all.

Level 6

Overall, this was a bit easier than 5, though I can see it would be tricky if the player isn't used to brained snakes and queens.

1S1W: A bit messy, I just tried it a few times and got lucky rather than formulating a real strategy.

1S1E: I had no idea what to do here until I noticed that I was slowly gaining on the queen, so I just kept it up until I got her.

Just to clarify, I am not replacing the two rooms in this level, only moving them to a later snake level and putting something else in its place for now. I figured given the number of rooms so far where you have to rely on the particulars of unbrained snake movement were so few that I could move them to their own level later, let people deal with the more complex mechanics at a later time. The other rooms in this level trap snakes in thin corridors, so I'm adding more rooms like that to this level.

Yeah while this hold isn't really aimed at new players, maintaining some loose sense of a difficulty curve by slowly introducing complexity would still be a plus.

Yep that's correct, a bit of an odd room, and no real puzzle, but I like it. It's like the world's least horde-y horde room.

×Right, yes I see now, I confused myself last time. I think in practice this room isn't about squeaking out the last turn of efficiency, but rather the trick that buys you a bit of time and so I think I'll leave this as is. Besides I always try to avoid adding more orbs where I can help it. At the moment the level already has its designated single challenge and while it's not a spectacular one, I think it adds more to its room than this one adds to this room.

×Second Level: 1E
Perhaps move the entrance orb one square south, to allow traversing the room from west to east.

Second Level: 1N2E
Nice non-intuitive trick.

Third Level: 3W
Challenge is definitely harder now.

Fifth Level: 1S
Definitely more satisfying now.

Fifth Level: 1N
Seems much easier than the rest of the level. Maybe modify the entrance so players will tend to go north first?

Fifth Level: 1N1W
Nice and tricky puzzle. In the final version, you should mark the path every 10 squares to help counting.

Sixth Level: 2E
Now the room makes sense.

Seventh Level: 2N1E
I'm not sure if this is a challenge scroll which should be behind a green door or not.

Eighth Level: 2N2W
Nice room, but challenge scroll should definitely be accessible from the beginning. It does not give away the main solution, and missing it would require repeating execution details.

Ninth Level: 3S1E
You can make the chamber between the red and green doors be a full rectangle. There is an extra monster which can be brought in.

Ninth Level: 2S1E
Is now much harder. Cutting brained tar while moving diagonally, and evading a serpent.

Tenth Level:
Nice balance between scary rooms which turn out not to be too hard to both understand and execute (if you understand serpent movement) and small simple rooms where the idea is clear, but the execution not that easy.

Tenth Level: 1N2E
I sent the serpent in through the west red door. Reviewing the demos, I realized that it would probably be easier to start in the east. Maybe a challenge?

Tenth Level: 1N
Challenge: Don't step on trapdoor in SE chamber.

Eleventh Level: 1N1W
When completing the challenge, I collect 13 roaches in the northern chamber. (Is 14 possible?) This means that completing the final stage of the room can depend on move order.

Eleventh Level: 2W
Challenge: Use only one potion.

Thirteenth Level: 1E
Challenge: Keep all mimics alive.

Fourteenth Level: 2E
Finally solved the challenge. Nice.

×1E: Simple enough, good choice for the first puzzle room.
2E: Fun combat room.
1N1E: This looked horrible, but I got an idea that I could use three awakened eyes to kill the serpent north of the isolated pit tile, and going for that solution ended up revealing a simpler killing spot.
1N: I remember this being rather confusing on first glance, but the conspicuous line of force arrows helped me realise what the room was asking me to do, and doing it was simple enough.
2N2E: I exploited a quirk of brained behaviour to win this one. Not sure if that was intentional.
2N1E: A little haphazard, but simple enough that you can try until something clicks.
2N: Excellent linchpin, I really liked this room.
1N2E: This was ridiculously hard, and could have used some more checkpoints along the way.
1N1W: Very nice secret variant where the solution ends up being completely different.

×Entrance: A linchpinny trapdoor puzzle, always a nice thing to see.
1S: No problems here.
1S1W: Fiendish secret! The sequence of moves to wiggle the roaches into the correct movement order was pretty hard to spot. At least you gave a clear signal that it was a movement order puzzle. Could use a checkpoint at (19,12).
1W: Fun little combat room. I like the fact that there was just enough leeway, and probably a few different ways to do it.
1N: Simple enough, but fun all the way through because the dropped trapdoors kept changing the nature of the task.
2N1W: Good concept, very easy to spot the route though.
2N2W: Some nice techniques for keeping roaches at bay with a few trapdoors.
1N2W: This was absolutely fiendish. Even though the solution turned out to be pretty simple, it was extremely difficult to spot and there were many other things you could try that led to dead ends. Still, it was a nice satisfying room to work out. Eastern checkpoint could move up one or two tiles to make sure you hit it before hitting the orb.
1E: I left this until last, but it turned out to be not very hard; just needed to work out which area for misdirecting the snake went with which edge trapdoor.

×Do not use the trapdoor shortcut at (13,15)-(16,13)

×Each of the 10 serpent clock states for releasing the serpents is possible.

×The challenge solution depends on the clock state for one set of actions. (Chaco will probably find this solution first, with or without attempting the challenge.)
A variation of this solution can move the dependency to a different action.

×In what I assume is the intended solution, searched for after Kieran insisted the room doesn't require knowledge of movement preference, no moves depend on the clock, and only the serpent circuit directions in the traps depend on NESW order. (Chaco should also be able to find a solution with these conditions if he tries.)

×Kill the SE roach and return through the entrance area.

×The key to all these solutions is to overturn an early assumption about the room.

×Yes, it's a good room. But way too hard for its current place.

A few things make it hard: firstly, there is so much choice in terms of order of operations and how to go about each step, it's easy to feel bewildered and find it hard to pick out the one approach that works. Secondly, the linchpin of going back to hit the (17,25) orb early is very well-hidden, when everything else in the room screams that you have to get from A to B to C... as fast as possible. Thirdly, of course, "a little learning is a dangerous thing"; when the main difficulty that you keep running into is that you cannot coax a snake west into (20,14), it's easy for the player who does know about snake preferences to think it's all about setting things up relative to the clock.

In fact, your hint that snake preferences were definitely not involved made the room much easier, less frustrating and more fun, since it forced me to focus on dropping the trapdoor to direct the last snake in there -- which highlighted the problem of getting back to (17,25) in time; and once I was focused on that, it wasn't hard to realise that the correct solution was at least something I should try out to see whether it worked. So maybe you should consider adding a hint scroll with this clue, even if you do move the room to a later level?

I found it a bit unfortunate that killing the roaches depends on their movement order relative to the snakes.

A couple of things I'm not sure about in bbb's feedback:

* bbb says that the challenge solution depends on the clock state for one set of actions. I don't see where. If he means releasing the snake at (15,22), given that (15,24) has not been dropped, then no, this doesn't depend on the clock at all (as my demo shows).

* bbb asks whether it's possible to kill the SE roach and return through the entrance area. If "the entrance area" means the loop where the snakes start, then it clearly is possible, but I can't see any way this area can be cut off, so I'm not sure how he can have thought otherwise.

×Overall, much more pleasant than expected from a tar level It felt a bit easier than Level 7 or 8, but maybe that's just because there weren't any super-hard rooms like 8:1N2W.

1S1W: This was pretty tough, I had a lot of tries that fell just short. Maybe add a checkpoint at (17,20)?
1S1E: Mostly a brained snake puzzle, but it's good that this quirk gets some focus as it didn't really come up in Level 6.
2S1E: Very intimidating, but fortunately the timer was very lenient.
3S1W/3S2W: Another excellent normal/secret pair with very different solutions. I was a little disappointed that neither room involved carving the tar so as to create three tar babies primed to kill the serpents, which would be another interesting variant puzzle.
3S: Very tricky. I spend a long while looking for ways to get two tar babies out of the SE chamber, before realising that I needed to start over and bring an extra tar baby from every chamber into the next.
2S: A great mini-puzzle to finish the level with a unique use of the blue door.

×You can coax a snake west into (20,14).

×I see. Then extend the challenge requirement to also have all four serpents locked up. The alternate set of actions is for the serpent at (15,23) staying inside its cell until it is locked. The original set is for (20,17)

×The idea is not to lock a serpent in the third cell, but to release it immediately, kill the SE roach, and get back on time so that the final serpent won't be able to escape the first cell.

2N: Blocking the tar with a small twist. Liked it.

×
Level 15 1N: I assume I need to change order of tar, roach and eye. They need to go north, then kill the mother and snake.
My best attempt spawn a baby in the way to north (else they cant reach the north) and when I reach the tar mother in the west chamber at south spawns another baby.
Level 15 1N 1E: Tried to do some timing but ended with a baby outside the tar mother area.
Level 15 2S 1E: tried to do a tar baby lined with the timer but left unsolved.
Level 13 1E: Finding a placement will take some time.

×I was fully expecting somebody to do a baby flood solution, and the secret variant has a timer explicitly to kill this, but I allow it in the main room so that it's not too hard and can be solved sufficiently from the secret variant. The secret variant is most likely the most difficult room in the hold so far.

1N 3W: Tricky roach queen room, my solution maybe is somewhat unintended
2N: Symmetry room, love it as always.
1S 1N: Took a while find the correct order.
1S 3W: Tight timer with the invisible potions around the maze.
1N 2W: Tried to do the wrong way that would be cool (guide the roach queen through the west arrow). Liked the room.

entrance: did the challenge, easy introduction.
1S: Strict movement with the wraithwing room, took some tries.
1N 1E: Maybe I did something unintended. Didn't broke the walls at all because I brought the wraithwing from behind.
1E: Some wraithwing manipulation to avoid eyes being trapped. Good room.
1W: Reach a position to kill the wraithwing. I Used the south trapdoor.
1N: Wraitwing manipulation to avoid roachs spawns. Favorite room of the level.
1N 1E: Block wraithwing for a while. Good room.
1N 1W: Block roach spawns. Liked the room.
1S 1W: More serpent manipulation than wraithwing. pretty good room

1. You must wait for the 3rd circle or the tar baby/roach and eye cant reach the north side of the west chamber.
2. 1st tar cycle position roach/eye/tar near the tar.
3. 2nd tar cycle position, creates a baby always. I didn't find any position which this dont happen. It doesn't matter due to the point 4.
3. 3rd tar cycle position, monsters in the west side can reach the north side of the room.
4. 4th tar cycle, creates a baby in the west side at south chamber making the room unconquerable because you don't have enough time to go north and then south to stab the eyes in the 3rd cycle.

×11 1N3W you did get the intended solution.

12 1N1E this solution was fine, as the secret room variant makes more use of the broken walls so it's OK that you didn't do much with them.

13 1E not a weird solution, actually the best solution I think I've seen so far for this room, as you don't get caught out by your own mimics. Well done!

×Point 3: "2nd tar cycle position, creates a baby always." is wrong. To help you with this:
