As a music guy, I must say that it's an interesting concept for sure. The visuals are absolutely top tier, one thing I would say is that the game could get a bit better in terms of game feel, for what it is it feels almost too quiet and I understand that since the point is to match the pitches you can't really blast a loud track in the background at all times, but you could maybe add a bit more sound effects and maybe some lowpass background ambience so that it doesnt feel like a website but like a game. I think if you would continue to work on this game after the jam ends, you should make the levels much smaller but more of them, so you can feel the progression faster. Anyways, awesome game, these are basically just me looking too deep into it, keep it up!
