Well, that was unexpected!
I feel the lack of clue numbering was detrimental to my enjoyment of the puzzle. I had cold solved dozens before getting a foot in the door in the NE corner. Even then, it was a slog to get answers positioned. I wasn’t too put off by the messages and alterations in the end game, and then I came to appreciate the abstruse clues. The absence of various indicators didn’t really colour my opinion. Overall a good puzzle that was, I think, overly daunting at the outset.
