Got stuck at 154 for a while before I remembered a core pipelining technique... The design is very pretty but could easily be condensed by a lot for mobile. The puzzle is great regardless.
While it's quite cramped, the number of potential paths is larger than I expected and I found a few 2-offs before reaching 109. A nice level of this style!
The first second and fourth sections aren't that hard if you have some pipelining skill. It's the third and especially the last sections that will get you.Seems like i missed a spot. It's funny i remember having that on my original nonoptimized one.
Now when I remember how to save 2 in the 3rd and 5th sections I can beat it. I'm 4 off. And manti, you are once again the king of psychopath. Edit: You're going to hit yourself for letting the record slip through your hands.
