Love it!
Came 6 off, then saw it was actually 2 off, and now kind of stuck (20 tries - did the beggining both ways).
Edit: Got it in 54th try. Good level!
2 off. I guess I'm really in trouble now... EDIT: Never mind, 13 tries, not counting fingerslips and forgetting to push the left side of the final lock (dunno why I kept doing that).
