BLAM!!!
I honelstly wanted to blam this game the first time I saw it because it pissed me so off. Fortunally it was so addictive, that I kept playing it and it became my favourite :D
Next time you could add something the blue balls can't go through...
BTW, I found a little bug in the game. When you get the turbo boost near the finish, then you will be jammed in the finish...at least I did.
