The music fits pretty well! And the concept of rhythmic movment for the platforms and obstacles is really great!
If there's only a suggestion I could make is to add come Quality of Life features to the jump. The famous "Coyote timer" and maybe to remove de "height penalty" to jump pushing yourself against a wall (Tha resistance made your jumps shorter, and some obstacles grow a bit frustrating).
But is a pretty solid game! Good work!
