I like the premise of this - I definitely get the "no text 3D platformer" vibes you explained from the prompt.
The music here is really nice! Both of the main themes are really pretty, and instrumentation and production brings up a notch to beautiful and whimsy. I also want to specifically shout out the arrangement of the last track - when that piano comes in? That's the stuff!
Great melodies and harmonies, great instrumentation, really nice aesthetic and overall, a great submission!
