This project is incredibly impressive, especially from a technical standpoint! The visuals are so well made -- love the vibe.
My only feedback is that if possible, add a loading animation or something while generating a new level from a song since currently it freezes the whole game. (I'm not familiar with the framework you used, or if that's even possible with it!) Other than that, maybe a volume slider so I don't need to turn down my whole computer's sound.
I think this is a really great game and technical showcase, well done!
