Love the choice of music! And a great idea for a game fitting the theme -- build your own platformer!
The play of the game felt a little unresponsive to me though. I would suggest that when you make animations/controllers you make the character start moving right when the player tries to move. It felt like I was playing in molasses!
Wonderful idea and cute execution.
Review my game in turn! https://kaleido.itch.io/balance
