I've just conquered this. Great hold!
There were many good rooms, but, unfortunately, there were some easy and not very good rooms.
×Slayers' Chambers:
1E: Start room. Showing how monsters react to the pressing power token or killing one of monsters.
2S 1E: Good room. Making the Slayer stab mud and not letting mud babies get you... good!
2S: Awful, awful(in a good way) room! I really liked it!
1S 2E: A little more easy than 2S, but still great and rather difficult.
Seep spaces:
Etrance and 1S: Start rooms that show how can swordless character kill seep. Well, rather nice.
2S: GOOD ROOM!
Gel has to spawn, then you have to clear all the gel... yeah, great.
3S: An elegant way to "
protect"
tar from being stabbed by briar. Nice. I liked it.
Imitation Grounds:
1N 1W: Wow. This is the most difficult room in the level(and maybe in the hold)! This is fairly difficult!
2N: Tunnel isn't required - there're two waterskippers, so you still have to use mimic to kill one of those after you killed another. Anyway, easy and nice.
2N 1E: Not too hard, not too easy. One of ways to use clones creating puzzle. It was enjoyable, however.
1E and 1S 1E: I found these rooms too easy. You just have to place clones on right spots(which is very easy) and then use those clones to kill other snakes(in 1S 1E you use mimc, but still, with help of clones).
Outpost 12: Quite easy and enjoyable puzzle. Every part of it wasn't hard but was enjoyable.
Tarstuff laboratories:
1W and 1E: Greatest rooms in the level!
Both rooms made you think and were quite enjoyable. Good work!
1S 1W: A little boring, but still nice.
1S 1E: Really like Seep Spaces 3S. But, as aumtlich says, a little harder.
1S: Reaching mud mother part was nice.
On the lake:
Etrance: Great room!
Making the mimic and adder survive until you have stepped on conquer token was a clever idea.
1N: Yet again, easy room. Nice idea, but can be solved very fast.
2N: I found this room the most enjoyable in this level. And the most difficult. Managing the snake's tail to be on hot tile while you're outside snake's line of smell... this is hard. Truly hard.
3N: If you understand which nests should you kill first, it's easy. But nice anyway.
