Did you know there was a simple trick to be certain to find the exit of any labyrinth (assuming you start outside of it and not inside of it)? It's rarely quick but it defintely will get you to the end without getting lost at all. That trick is to always follow the same wall, right from the start and never cease to do so, just like you're keeping your left or right hand on the wall all the way. Eventually, you'll get at the end. I tried both sides for your maze and, all I'll say is that one is definitely shorter than the other. Hopefully you'll pick the right one, otherwise you know what you have left to do. ;-)
