Tried to save 2 on an optimal ************* path for a bit. Never tried the e right side as it looked slower. Haven't beaten this yet, but it's getting a lot of discussion and playtime so I think it deserves the 5 star. Someone please find a 180. ************************************ Got me to think, good one :) I struggled solving the 2 off. Suddenly one routing worked. Why this one? Dunno... I was lucky here.
