I haven't solved this one, yet, either, but I agree with yokosooo, all in all! Looks splendid! And is a good puzzle, too (my first try ended with a terrible blunder, that couldn't bring me to even touch the exit :) ). AFter a few tries I came to 245. Will keep trying. :) Very interesting, IMO.
EDIT - wow, got it now, at meow's 227. Great find, meow. Very nice path. Not sure if optimal, though, we'll see.
