This is a nice rhythm game. The music is good and the button input timing fits the music. It's really hard to do the timing for rhythm game (moreover in short period of the jam) but this game successfully pulled this off!
I also love that the characters have dialogue in the middle of battle, but sometimes it caught me off guard and messed up my timing. This is not a complaint though, so don't remove it. Maybe add more funny one liner.
Anyway, this is a solid game. Good job with this one!
