Unfortunately I found the game very frustrating to control, it seemed like the whole gimmick of punching the ball was unreliable and hard to use. You have to get pretty close to the ball to hit it but too close and you nudge it then you have to chase after it.
I also found moving while jumping lacked control so I'd fall off ledges or fail jumps but discovered I could punch walls to scale them and that was quite fun so maybe you could utilize that in some way?
I do see potential if you tighten up the physics and allow the players to do some crazy moves, for example I used the tiny ball and managed to uppercut it to the top of level 8 but since there were no rails up there it just rolled off. Finding ways to use the physics to your advantage is always fun for the player but when the physics are hard to pin down it just makes it a pain. Perhaps simply getting the ball to the end would be a good solution since you don't have to babysit it till the timer fills or make the timer shorter?
