Wow, really great job on the visuals! It looks gorgeous.
And it's also cool to see a rhythm game in a jam! Maybe the game could use a bit more of feedback, I never knew really when I hit a note and when I missed hit (if there is a color difference, my colorblind's eyes didn't see it :p), which eventually didn't make me feel following the rhythm at all. But I liked the simplicity of the controls, and the intuitiveness of the gameplay loop. Congrats for making such a cool game!
