I came to this page, thinking I was on Easy, so the fact that there were only nine comments meant that perhaps the world had come to an end. I was delighted to realize I was on Tough, where nine comments is almost chatty.

I was delighted by this puzzle, too. I don't recall ever seeing a pattern like the one this had in boxes 4,5, and 6.
