Must be the world's shortest story. "The knight walked off the screen." Sorry, this is not a "real game." It has no gamelike qualities whatsoever. I blame you, VILIUS2000.
The instructions don't seem to have anything to do with what happens. If you touch a black box you get points, if you touch a red one, the game ends. Nothing changes the rotation of anything. and no boxes form the corners of any square.
Thank you.
