Really amazing level, best in the series for sure. I found 3 paths that are optimal at 97 before finding the right idea. Even then it took me a bit to cut off the last two moves.
I love such levels.
I had a good laugh, because I was working on all the 2-offs, when suddenly one route won! But why that specific route out of all those I tried? Not a clue... Wonder if I can redo it LOL.
Edited 5 mins later: OK, I was able to redo it, but I still don't know what I did different. Only thing I can say is that this is one more case of "longer is shorter" at one given lock. :D
Two month ago, I got it in 1st try. Today, wanted to replay it, and - took me over 20 tries. Just couldn't find the last 2 cut (to get 79). GREAT level, IMO!
