Very nice! Didn't realize you could change directions, so I was bouncing off the walls to change directions. It made the 3rd level funny because I was bouncing off walls to stay on the moving platform! XD
Adding the "Z" key to change direction was very helpful (just like reading the directions haha). I did notice an issue with the moving platforms that when my character should have landed on it, he just fell straight through.
Fun game! I really like the concept.
