I've only been able to get up to the eight level. The long jump has taken me at least 170 attempts to beat, all of which have resulted in my character missing the ledge by such a small amount after jumping as late as I can. Even when I try the ball, it's so impossible to control that I still fail -- I can't even make it to the platform.
If it wasn't for that level, I would absolutely love this game. But that level is just impossible due to the (nonexistent) controls of the ball.
