Oh dear. It looks like I've reached the limit of my playing abilities on the third level. I thought I was pretty OK with snakes, but these puzzles have proven otherwise. One of the rooms I cannot solve is required, so I'm stuck now. (I don't playtest in the editor, where I can't save demos of my work.)
Comments on Tricolor Trial:
1N - I solved this room the messy way, one serpent at a time. I suppose someone will figure out how to do both at once, which would be really cool to watch.
1N1W - I positioned the serpents so that I could wake the eye exactly 8 turns after becoming visible.
1N1E - I did this the long clunky way, placing one mimic in the SE corner, and one decoy in the NW corner to keep the mud cuttable. I waited until the adder was dead before dropping the trapdoors.
1W - I ran through the bottom loop 4 times. Twice when I had a rattlesnake stuck on the pressure plate, twice when I had him looping on and off the pressure plate.
2N - The serpent helped me get the roach out of the middle chamber, so I didn't have to step on its trapdoor.
2N2W - I used the fact that an adder's tail doesn't move when it's eating to get 4 roaches out of the western part of the room.
3N1W - I'd have no clue how to solve this room the intended way. I dropped two trapdoors by the entrance and waited on the SE tunnel until both serpents were dead.
I need help with 1N2W, the last required room on this level. The room is covered with hot tiles, so I can't turn Beethro's sword. There are no dead ends or even corners where I can fry the adders, so they must all be killed by cutting. It's easy to kill the NE and SW adders (or the NW and SE adders), but the other two are another story. To cut them, I think I need an even number of squares between Beethro and the adder's head, but I always have an odd number. How do I change that?
By the way, Jutt, if you'd like to see any or all of my poor clunky demos, please ask, and I'll post them here.
