Hey! I have some feedback for your game!
I wish when playing as a circle on the first level there'd be fewer jumps.
I also wish that there'd be coyote jump ( you can jump while not being grounded if you were grounded like 0.1-0.2 seconds ago )
Lastly, I wish you would not need to restart the game when you beat the game as a square.
Fun game.
