Cute game, I liked the jump and then rotate in the air sections. Its was fun when the game broke also I had like 5 dudes walking around before everything went black! The difficulty curve is well balanced and it doesn't get too complex by the end. Good job!
If I were to change one thing I would make the visual hints for the rotation controls a bit more clear. Something like this:
Make them in a way that clearly show the player A: which key they have to press and B: the direction for the rotation. I feel like downward arrows are more easily understood since you can imagine them pushing against the ground, a very natural and intuitive action.
Other than that very nice and sweet game! I usually don't like platformers but this one was nice.
