Congrats on your submission !
There are a few little things that could need a little more polish in terms of gameplay in my opinion. First, the camera should be way more to the left, as right now, half your screen is useless because it shows what you already went through instead of showing you what you're going to go through. Second, my guess is that you use move_and_slide() for movement, and check if you're on the floor with is_on_floor(). It would have been a good thing in your game to change the value of the floor_max_angle of the move_and_slide, to detect is_on_floor even when your character is on a 45° rotated platform ; that way you could jump when your platform is rotated and the gameplay would be way smoother.
