Move around to draw your path. You cannot walk twice on the same spot.
If you cannot move just hit A to go back to a previous location without erasing your path.
This will allow you to fill the screen with a beautiful maze. See attached screenshot.
Or just press B to see it self building in live.
See follow the recursive backtracker algorithm to generate the maze.
Comming next a way to save it for another game :-)
