Cool game! I ended up playing this several times. I did encounter an error on level 4 twice where I tried to go into a new room and the screen goes to black and effectively freezing the game. If you get this fixed, please let me know!
Thanks for the feedback! The level generation was in for a redesign anyway, so i'll fix it as soon as I can. However, I am currently participating in a gamejam, so the fix will not be immediate.
