A very clever take on the rhythm genre of games, I found this to be fun and after a short while, quite intuitive. I wish there was more variation in the hit sound effects so that the confirmation of being on beat wasn't strictly visual and could be derived using the sense you're already tuning to the music. Some death animations would have been nice, but I'm sure this is something that had to be scrapped for time. I also wish the jump kick didn't pop up on hit, making it pretty hard to utilize. Ideally it should come down on the enemies instead.
All in all very clever game with cool graphics and animation. An impressive level of polish too. I'd love to see a more fleshed out version of this after the jam. Great work!
