Good puzzle. Odd thing - I saw the CTC link and it was from a while ago - and I commented on it that it took me 20 mins back then. My computer had no record of that solve so I just did it again in a little under half that.

Just over four and a half minutes. They're easy puzzles, but I'm getting better at them over time, especially with some obvious starting points.
9x9s from you are rare, no?

Tricky end but a smooth 16 minutes overall.
