I did it. I hated it. Am just glad there is no traps and it's just a matter of paying attention not to do extra moves by accident. The one star is because I did it while hearing a boring conference call and it helped me staying awake :D
I enjoyed solving this. I was stuck a long time 6 off, with no more ideas about what to do, until I told to myself: go as easy as possible with a minimum of blocks touched. And I won on first try doing just that. LOL
