Gosh, what is this?! I can't do any better than 2 off. It feels like caressing a hedgehog, after so many tries. ;) Will come back, later, but giving stars, already. There's obviously this ''blind spot'' that I have, in certain levels. When I just cannot see, how to do it optimally. O:)
Great find, David!
EDIT (about a year later): I finally found the 99 path. It seems so easy, now. lol
