Also 2-off...
Really wonder what else I can choose... Edit: After 4 months, finally decided to do something different, beaten finally :) :)
Time to take a rest now.
Unexpectedly, saved 12 steps... picking the correct blocks in this kind of levels is always fun :) lots of possibilities
(reply: Don't know which path would lead to 281 too, after finishing quasi-crystal, I found the path there could be implemented in a similar way, so got this immediately).
Nicely spotted :). I haven't got a clue what my original 281 path was on this one :x.Can't see anywhere you can really lose 12 moves on it in one go; and I can't see an alternate path to 281 :\
agree with what neemo said, difficult to figure out what you should push if not analyzing enough... and now I am 2-off several ways... EDIT: got it, was taken the false path overall, those false path just seemed so fitted into the level when I don't know the right one.
This level used to be impossible for me to beat. I forgot all of my routes between now and the last time I played it, and I beat it in four tries. I hope this means I've improved.
