takes awhile... hard to tell whats "shorter" while !wall(AHEAD): move forward turn left while wall(AHEAD): turn right

  If you started off facing a wall your code would just not do anything. You can both simplify it and fix this bug by reorganizing the loop. while true: turn left while wall(AHEAD): turn right move forward However, while this algorithm happens to work on this maze, it will not work against other mazes (if you care). Imagine a 5x5 square race track, with spokes coming from the outside of the wheel to the center, where there was a flag. Your algorithm (and my modified one) would just spin clockwise around the track without ever realizing it should take a right towards the center.
