That was a neat prototype! I like the echoing thumps in the song; it enhances the feeling of being stuck in a labyrinth.
Sometimes, when I opened the game, I'd be put into a two-room hallway with no way to get out.
Congratulations on the submission!
The initial plan was to have multiple floors in the dungeon that progressively got harder. With that in mind, the two-tile mazes would have been unlucky (especially early in the dungeon), rather than feeling like the game glitched out.
(Technically, none of the mazes have a way out yet, anyway -- it's just most noticeable in small floors)
