This program uses the "recursive backtracking algorithm" for generating a maze. A description of this algorithm can be found here: http://weblog.jamisbuck.org/2010/12/27/maze-generation-recursive-backtracking After the maze is done, use the arrow keys to move the cat to the cheesy puffs. To make maze generation faster, shift-click the green flag to enable turbo mode. After the maze is done, shift-click the green flag again to turn off turbo mode so you can walk around the maze. (You can also set the BACKTRACK DELAY variable in the code to 0 to make the maze-making faster.)

Keep moving in that direction. 3) If you've backtracked all the way to the start, you're done.
