On level 10, there's a bad glitch where the ball slips off the poles no matter what you try! Once you get to levels like 11 and 14, it's bound to get too hard for almost all ages. I haven't even pasted level 10 yet because of this dreadful glitch! There's another dreadful glitch also. I think I could make a list of the world's top 10 worst glitches out of this one. Sometimes, the screen freezes and the the iPod shuts off. Then I have to start over the WHOLE level I've spent 15-45 minutes on! Please fix all of these glitches! It could be a 5 star app. And they should have more than one type of music. It's fun to listen to, but when you have to listen to it the when you have to listen to just that one song the whole game, it gets very annoying. But on the other side, this app is very addicting.
