I have needed 891 tries until I found it. Don't give up. If it can help a bit for those stuck on it, 2 hints: 1) Generally, the straight way is not necessarily the shortest. 2) The level is to be solved in the lower part.

I was very fast at re-winning it. It was crazy! My fingers were like possessed and redid the way in automatic mode, without me having any control on that. I suppose that I had so much worked on it at the time, that somewhere in my brain, the routine was saved and respawn spontaneously! LOL
On a side note, the two hints I gave 11 years ago still apply.
The main difficulty in this level is how to deal with the middle-top part of the level. You have to analyse this level by its end. There is only one part here to optimize (there is another one which leads to a 2 off) and the tricks are quite simple so don't waste moves there and think about the fastest way to push the block as always.
Another GREAT level ! 68 tries brought me to 2 off. Will keep trying. Edit: 119 tries to ''Pushover''. When I first saw it, I thought It's not possible, at all. :) Took me quite some time to figure out the path and almost twice as much to optimize it.
omg how didn't i originally tried that. amazing, i really did find a completely wrong 2 off path! thanks nielssss for the motivation to actually solve this the right way! and finally once again i am 100 percent!
