(somewhere in May, 2023) I think this is a great level.
The only problem is, that I still can't solve it.
Will keep trying! :)
EDIT 2023, 26th Oct: 5 months later I finally saw HOW to do this one. GREAT level, indeed! :)) (I was looking for the right thing, but just couldn't see it, before.)
I had fun solving this board! I started on one side, but the route was so long and needed to move so many blocks... It was clear I can't make it on this side. Then the comments told me there are other ways than what I do. So I tried on the other side, and was very rapidly 8 off, down to 4 off and winning straight after.
So, without spoiling the level: there are several routes and only one can be optimized.
