FINALLY I HAVE WON!!!
After about four hours of play I have defeated all 50 levels. The password for level 50 is FULL-TIME. It was fun and challenging. The hardest level by far was SAVAGE. However it seemed by the end that you guys just stopped caring and just made levels to clear with no trick to them at all. Also, you should be able to change the ball's speed and direction in more ways than just hitting it with an edge. Anyway great game. Miniclip rules.
By the way for those of you who had trouble with level 48 (the one with the seahorse) it was just a glitch, but it's fixed now.
