Not as impressive as I hoped; it felt like most paths I tried, instead of being slower, were simply made to be impossible. So the level ended up feeling like a time-waster more than a puzzle.
Still a pretty good solution.
That was magic for me this one: I was 2 off for a while, and started to re-trace each of my 2 off paths slowly, to study where I could possibly save 2 steps, and suddenly, I won! 0-0
Since I thought I was redoing same than before, I have not the slightest idea what I did different allowing to save 2 steps... LOL
Everything is 4-off...
However, every incorrect path gave me the distinct feeling that it couldn't be right, and the solution itself wasn't very fulfilling.
I have big fun working this level through. Have just found a 2 off. The real challenge is starting for me... :D
2 tries later, I got it! Great one really.
