Super cool idea and great game! The music really comes together too!
One piece of feedback I could give would be that when I first saw that the fruit loop was able to move and had special effects applied to it based on instruments (like jumping really high), I was really intriguied and found it such a cool mechanic. However, if a player were to get frustrated in the first few moments of the game, they may not see this moment and really understand what makes your game cool. Maybe you could start with an extra easy and short track for the first round to guide the player to your games cool parts, so they can play for longer and have more fun!
Great game overall, really enjoyed it! Well made 👏
