app generates a random maze, can define dimensions and number of rows or corridor width user walks through the maze and can't see it when user hits a wall, big red x's and sound like on family feud if user clearly walks completely through a wall the game ends, or at least it'll stay red and sounding until they get back, maybe give an arrow pointing to where they need to go to get back uses gps problem: gps only works to within about 10 feet precision, I think.
