This was sooo good!! I liked the concept that in each level you would go up against a few enemies. Made it feel like I was actually progressing through a dungeon. I also really loved how each enemy had their own little unique tune. Also good job on having so much content for a jam game (5 distinct levels!) Another thing I liked was how different parts of the characters were anmiated separately and danced around. The music was also really nice, good job for creating it custom.
In terms of feedback, a good tip for rhythm games is to have everything pulse/animate to the beat. It makes the game feel more alive. Also it would have been nice to have more feedback when hitting/missing notes. Most of the time I didn't really know whether I was making progress or not. Also this is kind of a nitpick but sometimes the levels felt quite long and would feel a tad boring after a while.
Excellent game overall! I love rhythm games and actually made one myself for this jam. I was wondering how you authored the levels/notes for this game? Was it hard coded or did you have a tool or maybe import MIDI?
