From someone who wanted to get into a game design career (never happened due to the hand life dealt me) i gotta say this is actually well designed! I mean i wasted like 3 hours on this even though theres not really a whole lot to it to warrant that.
The pacing of the story and game play is great. The mechanics are simple enough where its easy to grasp, but intricate enough to have some variety.
What took me by surprise is tou made the game with what i call interactive music (idk if theres an official term) the fact the music swelled (pun intended) to more complex variety of instruments and notes as you grew larger was a nice touch and likely what encouraged me personally to keep playing.
You’re a person of many tallents, really i applaud you. Great game direction, great game play and talented musician. Kinda inspires me to try getting back into game design.
