The level is fun, but I badly struggle with a 2 off for now... :(
** loads of months later ***
I finally solve my 2 off. Am so happy!
Like said by many others, the center/bottom section is a killer! That's where I was losing 2 steps of course. In my case, the solution was of the type "seems longer, is shorter". I found it while forcing routes I knew wrong, just to release new perspectives: I suddenly had the surprise to arrive at one specific exit with 2 steps less than usual... I couldn't believe my own eyes... LOL
