Really liked the mechanic! Art, audio and level design was good. The twist ending was fun. Sometimes the dungeon piece would only move a little bit, usually dragging another dungeon piece with it, putting them in odd positions. Also got myself stuck in a corner once with soft-locking, but that's probably intended. Thanks for adding the restart button.

I'm aware collision checking is super buggy, it's definitely one of those things I'll need to work on for the post-jam version... right now I mostly tried to hide the issues by adding grace ranges and designing levels to avoid causing the edge cases, but there's a bunch of inconsistencies where the same action randomly succeeds or fails depending on what the maths feels like. I rolled with Game Maker's built-in collision system to speed up development, but it'd probably make sense to have my own grid-based approach for more control (rooms only really move in tile-sized increments anyway)
Glad you enjoyed the game despite the issues though! ^__^
