That was AMAZING! The idea is so unique and fun! No lie I expected some simple dungeon crawler but fortunaly I was wrong. I hated 2 things in this game: one of them is the friction that keeps me from moving between corridor walls. I quit because I stuck in level 10 or something (2 or 3 levels after slimes came) and couldn't move. The other thing is that door shut sound. It is annoying and too loud. But if you fix the friction problem with creating Physics Material and if you add your own graphics, that game would blow in the future. A little polishing, this is what it needs. Good job!
