Straight forward, it seemed easy to get on first try. Which is lucky as I don't think I'd want to do it again. Just be careful to make enough blocks available to fill holes.
Although a lot of moves are forced I think there's enough free movement to hold up some of us, particularly beginners, for whom it might be a good example of learning directional blocks.
I've attempted this so many times and ended at a 2off. Today I try it once and get 65 steps. I'm sure it's the same route I've used before resulting in a 2off???
I had a rough idea of how to finish, but not a complete path in my head, luckily options seemed a bit limited and I got it. Not on first attempt mind you, it took a few.
