Oups, that was your level, Flashback. I wondered why that one was in my unpublished levels so I decided to change it a little (a second version is coming). Maybe it's time to delete this :D
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.
