First try! I was lucky to the 2-cut right away, but it was still a very nice realization. Although the layout is a bit overcomplicatied, the logic is quite cool.
19/43. With today's levels, this would probably be a Medium - once you get the 2 off, it's clear where the pipelining is to be found and that's relatively straightforward by today's Mantipulation standards.
(14 years ago) 2-off again and again... don't know if I will try it later... edit: beaten, oh pipelining technique required.

Loved it. Lots of patterns can bring you to the end... some being shorter, of course. This is quite rare in a half-lock type level. And the pipelining trick is good too.
The abstract logic behind that 2-move cut is really weird. Now that I've thought about it, however, the shortcut is a bizarre type of pipelining technique. Hint: This puzzle's solution has a twin.
