I forgot about the cross indicating a "liked" puzzle......so wish to convey that I did like both 7x7's today

I'm still getting used to it existing but it might be helpful to add it next to the "(Note that you've already solved this puzzle)" or somewhere else on the page because I've missed it a few times too.

I'm not sure that I especially liked today's (8/27) 8x8 difficult but I did think that it was unusually difficult for its type.

I find myself liking every difficult puzzle I solve simply because I am filled with feelings of success (reinforced by the endorphin rush of finally seeing the familiar all-green puzzle ), so my "like" becomes more a reflection of my ability than whether the puzzle is intrinsically interesting or clever. If the purpose of liking puzzles is to train an AI to design better puzzles, I suspect my contributions are not helpful.
