2 tries for me. The 1 off path I tried first had clearly no room for optimization, meaning it can only be the other side. A look at the other side made it clear what side of the exit was the proper one.
One of the exits can be discarded without even looking at the level, which sort of defeats the purpose of having two exits. When you cut out all the fluff, the actual content of the correct path is pretty cool, at least.
