This was surprisingly easy for a Masters level. All of the steps are very logical and there’s pretty much no optimization here. Fun path to work out though, and cool that you could accomplish this using only one-ways.
Very neat level. Once you get the first few moves done, the rest of the level is pretty much forced, but finding the correct first few wasn’t immediately obvious.
I very much like this level, but am 2 off since ages and can't find any cut...
** one year later **
I came back to it yesterday and found a new route to be 2 off! It was really a surprise and I had big hope that this new way to go allows for a 2 steps saver. After some work, I found the 2 steps cut, in a - for me - totally unexpected location!
So, for those stuck 2 off, I can give a hint: at a certain location, we tend to push block off the road as it comes, without to think it much through and that's an error, because there is a way to park them aside that ensures a 2 steps saver at a later time... :D
