This is not the classic Sokoban that I am thinking about, but it is still quite interesting - 228 is best I can do at the moment, and I have ran out of ideas.
Reading the comments section, I have no idea what the original stepcount was?
yfkd did the 224 nine years ago but all the comments are older than that.
In the sectioned levels, it is really great that one particular section stood out to be the most difficult part.
That part really needed much consideration on the what and when to push.
I always appreciate alazeh's tremendous effort on level solving in the Psychopath 2 era, when we didn't have the undo button. In level like this, if level editor is not used, it would mean alazeh has to repeat the previous sections a lot before coming to the difficult part to try again!
