To design your maze's layout, open MazeGameLayout.py.  The grid of numbers in the file is your default maze layout.  Each number represents a different object in the maze: a space, a block, a pellet for the player to collect, a monster that will kill the player, or a finish line.  The object that each number represents is also listed in the file (SPACE = 0, etc).  

To change the layout, simply change the numbers in the layout grid.

The maze layout has two requirements:

1) The entire outside of the maze must be either blocks or finish lines.  Otherwise, the player and the monsters will be able to exit the maze.

2) Each line in the layout grid must have an equal amount of numbers in each.  Each line in the layout represents a row in the maze, so each row must have the same number of columns.
