Wow, that's a really weird path. Nice find and break by David. I do like the original 61 too, if only it was optimal. :) Hahahaha! Good one! First solving the puzzle as how to go to the exit, and then optimizing. Fun. Great 57 by David, here. I wasn't able to see it very fast. :) Was stuck 4 or 6 off. Had difficulty to get to the exit in this one.
