A free action game is called Unwanted Gray. Both too much light and too much darkness can occur. Real players are aware that the solution lies somewhere in the middle. The solution is gray, as they say. But occasionally even gray is undesirable. In "Unwanted Grey," reality is a gigantic kaleidoscope, and you are just a little node speeding through it. You are a flawlessly grey dot surrounded by power discs in black and white. You will be followed by the discs, who will infect you and change your color.
