After 16 years being 2 off, trying billions of routes, I finally solved this level.
It was a simple row of blocks vs. a simple column of holes but I needed 16 years to get rid of it and I can't even tell what I did different 5 minutes ago that saved the 2 steps.
I'm not even happy. I feel relieved, that for sure, but the main is an intense feeling of frustration.
The 78 route(s) were easy to find. The 76 route gave me a hard time. In retrospect though, the solution follows logically. If you get stuck two off on this one, you're probably closer than you think
