That's one of the best uses of that trick that I've seen. I don't know why I didn't see it before. I was on the wrong path the entire time. Great level!
WoW !!! 86th try finally brought me to 2 off (was 4 off three different ways, be4). Will keep trying. Edit1: Found another 2 off. *-* Edit2: 158 tries and it's DOOOONE ! :)))) Excellent level !
