Interesting Idea. Since the collisions cause the ball to rotate in directions other than the direction you're scaling, I'd suggest either adding barriers to prevent the ball from rolling off the platform or limit the direction the ball can roll in depending on the platform. I also think making the game 2D like Daemon's comment mentions would work just as well if not better as it would simplify the perspective and maybe simplify the controls as well.

I'd try having the direction of the boost go in the direction of your mouse relative you the character
