This is a much simpler approach to maze-solving than the original. This just implements the "right-hand-rule" - the mouse just follows along the wall to his right. This method, unlike the original project, which uses lists and is based on depth-first-search, does not solve every possible connected maze. (Of the six mazes available, it won't solve two of them for some placements of cheese - see if you can figure out which two mazes it can fail on. You can advance through mazes by choosing a different backdrop for the stage, or by simply pressing "m".)
