I like the ambition in this one, though it feels the jam's very short time might not have been enough for what you had in mind? I had a few bugs (possibly related to my computer), such as no sounds, and some later levels seemed to have, eg enemies shooting from outside the arena, or the player being left in a previous room? I really liked the art, and liked all the different attacks! I wasn't sure what each did, but they looked interesting. I'm listening to the music mentioned in the credits, and I think it would fit your game very well. The main mechanic is well implemented, I like how the demonic form goes towards enemies and then attack them! The first rooms play very well and have interesting designs, and the game seems to have a cohesive vision in its art, design and gameplay, great teamwork!
