Reverse Dungeon — Turn the dungeon, save the adventurer
Reverse Dungeon
You do not walk. Turn a floor, and the adventurer steps only when a single door is open. They live by walking into the exit. A pit that slides under them ends the run.

How to play
Choose a lower, upper, west, east, south, or north slice and turn it left or right. One step advances only when a single door is open. Walking into the exit wins; an exit that rotates underfoot does not. Walking into a pit, or a pit sliding underfoot, loses, as does step 24. Auto step starts off, and the view button does not change the board.
Origin & history
Reverse Dungeon is an original OIYO puzzle where you leave the adventurer still and turn the architecture by quarter turns until they reach the exit. Four boards were checked by hand; a seed picks one. It uses no map or audio from another game.
FAQ
Does the same seed always build the same dungeon?
Yes. The seed picks one of four boards that were checked ahead of time. The board is not reshuffled every frame, so a shared address is the same puzzle.
