Amazing.
I remember being 13 or 14 years old and playing the first Punk-O-Matic with my cousin at his house.
This game is painfully addicting. I honestly don't think I can say more then that.
I had a bit of lag here and there. But turning off the stage lights and lowing quality and animation helped a lot. (Thanks for suggesting that.)
I only have one question.
When you play a concert. I noticed that some of the balls are dark brown. What's the difference between the brown balls and the yellow balls? (Other then the color, ofcourse :P )
