The game looks amazing! I love all the art in this game. The player felt smooth to play as, and the animations/particles were all pretty nice. I enjoyed the gameplay, and the elemental fusions were really cool. Some things which I would like which have already been mentioned by others, is that it would be nice if there was an objective in this game. More enemies would also be great, though I can understand it being too time consuming for a gamejam. I also have the same issue with the music/sfx where the sfx is much louder compared to the game audio. There should also be more feedback for the doors opening when you clear a room. Apart from that, the content in this game is already pretty fun, and it would be awesome if more got added to it. Nice work!
