    Map Creation:
    the maps are saved in maps.json
    a map looks like this:

                [
                    [1,0,0,0],
                    [1,0,1,0],
                    [2,0,1,0],
                    [1,1,3,0]
                ]

                0 = free
                1 = wall
                2 = player spawn
                3 = goal
