Hint 1
The middle portion of the level is probably a little too cramped for what you're trying.
Hint 2
This one uses a trick that none of the other levels do. It should be pretty easy to set up once you're on the right track, so don't spend too long on anything that requires tricky sokoban maneuvers or complicated piece arranging.
Hint 3
Is there any other way you could move a block to the right after getting it into the tunnel on the left?
