Specific things I've noticed:
- - Snail King's room: Metal door sliding through wall
- "Will not leave with the flesh of my brothers:" Very cool idea, but player can just set them down, sidestep back onto the plate, pick them all up and move on as normal. Maybe move the door one tile into the tunnel and have a second plate as a check?
- Coming back up from the secret area of the level 8 (dropped down from "Four Corners"), the skeleton patrol pinned me on the stairs and I had to keep taking a hit, running downstairs, running as far away from the stair as I could to "lead" them, then back up the stairs to take another hit and do it all over again (they never really moved away). My suggestion: create a row of blockers on the inside of their room, then a hidden plate that deactivates them at the top of the stairs (Activate Once, by player). That will keep them from wandering too close to the stairs until the player arrives (but will allow them to follow the player to the stairs, if he's foolish enough to back up there).
