10 20 or 100 that's up to you . If your levels are small I would make many of them, but you have big level often 20 (I have done with me 20 - 25 levels)
I will do 20 first on my games and then so on, but I have another question how come is that on my ball going up, up up side ways, and not staying at on the ground? how i can fix it?
