(10 years ago) Took me around 100 tries to get to 2 off. *-* No ideas, left, but - Will keep trying ... Edit: almost 3 years later, and now I've found THE 2 off. And now it seems so logical! :D GREAT LEVEL! (429 tries).
*********************
EDIT 2023, 6th March - I'm so happy to have it cleared, again! :) Still think it's a great level!
After years not touching it, I did give it a try again and cut the last 2 steps! Soooo happy.... This one is of the type: "Path is right, moves are right, but somewhere, sequence of moves can be swapped to save 2 more". For me, such cases are the most difficult.
Wow, interesting... This makes me think of Battery (although I am still 2-off on that). Originally my impression is that this level only need time to polish your path, but not having the many 2-offs that brings me trouble in master world... edit: beaten again, my record is so short-lived haha
OK, done breaking it. Summary:
general route is gone. But still a good level! Bottom: complex, chances for new routes and more pipelining
Middle: already used pipelining, but maybe could be improved and still complex. Top: more straightfoward, with some simple cuts. Overall, great level.
