Just had another idea! you should make the music affected by the player movement and actions, similar to Ape Out, the Devolver Digital game. that game has a jazz soundtrack, and when you hit something or throw something the drums crash in and it makes you feel like your composing the music. I think this would be perfect for your game, as you could have a beautiful melody lightly playing when you're floating in the air, and have piano keys play when you hit a wall, so how you play determines how the music sounds. If you're able to gracefully soar through all the obstacles, the music will come out gracefully and smooth, but if you continuously are hitting walls the music will come out louder and faster, creating a sort of controlled chaos. Love the new levels btw!
