I genuinely had fun playing your game !
I really like the vibe of the visuals, I love the design of the first opponent, and the music!! I had a bit of trouble figuring out what to do on the first run, and I still wasn't sure if rhythm was important, because when I tried to reproduce slower movements at the same pace, I didn't score very well compared to other movements.
All in all, it's very nice, congratulations!
