I struggled with the controls a lot, especially since you designed the level in a way, where the platforms were often right on top of each other, making it very difficult to move fast enough to get up there without falling. Maybe you could add some easier levels to the start, to ease people into the controls to make difficult jumps like that less painful since the player will have gotten some practice before.
Besides that, I like that you came up with a new concept of being unable to move after hitting walls :)
