I found it to be a little challenging as my instinct is to jump whenever I've reached the next platform, and even had a laugh when I shot myself off the platform when trying to reach the star. I agree with Sock Puppet Studios on the bug that allows you to jump while mid-air. I was able to reach the star on the "You Win" screen using it. Perhaps there should be a check to see if the ball is airborne when pushing the jump key? Other than that I enjoyed it. Good work!
