It is better than the other 2500 step levels, so it is not the worst enjoyable, had a 2 off initially Same as alazeh and dead0ne, I thought it was impossible at first... only after I read the comments I am able to proceed It was confusing to me on which block is to be used. I was nearly double of the optimal step when I first solve this haha I believe there's much more steps to be discovered in this deset puzzle.
