From the "help" how could we figure out that the "chance stones" are lives and game over if we run out of them? How the heck could we know, except with trial and error, that if you hit the opposite side wall or if your balls *first* touch is a wrong color you lose a life? This is basically a patience game as theres no any freaking way other than waiting to get access to the color you have or a color changing ball, and you cant choose the color of the ball youre shooting?
Not one star because it is still a little bit fun. But I deleted it after 5 levels.
