This is such a cool concept! Great creativity
It reminds me of games like Beat Saber or Geometry dash where you can use the rhythm of the music to your advantage to anticipate the game, but this is better.
One thing that frustrated me is that the longer you took on a level the more was music falling behind everything else (the world obstacles and the midi board). Perhaps there is a extremely small delay in the loop that accumulates over time.
One thing I would maybe like more is to keep one beat/song for longer, because just as I got used to the beat and associated sounds with the colors I beat the level and I had to re-learn the associations again. And what felt really good was being able to (almost without thinking) predict the platform appearing/disappearing, and this cruising is what I think could make this game amazing.
Anyways, exceptional work!
