I really love the concept. A mini-map would be very helpful though. Audio is just not there in my opinion but, with these jams audio is usually later thought so it is understandable. I would love to see this game worked further(Perhaps procedural generated dungeon?).
It took me few tries to understand what game wants. I couldn't tell first that I can't kill Demon and I'm suppose to kill other beasts from other dimension to sacrifice. Game does require more clarity.
Lastly the art and theme is just top notch. Only thing I would suggest is perhaps the game is bit too bright for itself. If it was a bit darker I feel like it would be even nicer. Overhaul very nice game!
