This game works with Python 2 or 3, though you'll need the Pygame framework first. This game makes use of the MooseGesture mouse gestures module I developed.
Draw out horizontal, vertical, or diagonal lines in the same directions that the dot moves. The pattern of the dot's movement becomes longer and longer.
