In a world of colored shapes, a giant black shape appeared. This Black shape have sucked all the beautiful colors from the other shapes and turned them to black shapes. Until a day when a white color circle appeared. This white circle can give the other shapes some white so that they can return to their original color. The shapes have become somehow like the giant black shape, they try to suck the white color from the circle to turn it to their color. So the white circle must not make contact with other shapes for long time. In the process of donation of the white circle to the other shapes, the white circle loses white. So the circle have to regain the white form the white color source. The giant black shape can also suck the white color from the circle, so the circle have to avoid contact with the giant black shape too.
