In this game you're a demon in paradise. You need to fall down to hell breaking the floor of numerous rooms. The floors in heaven rooms are made of tiles. When a demon steps on these tiles they corrupt. The exception are the tiles near the walls. You need to corrupt all corruptible tiles to make the floor fall. You cannot step on the same tile twice, you cannot step on tiles with obstacles and you must push angels away from your path to step on the tiles below them. If something goes wrong, you can always restart the level.
