Lovely puzzle. The break in took me a while but after that everything flowed nicely.

What a lovely puzzle! We messed up a couple of times and went back to restart from the beginning but the reward was worth it. The negative constraint was really helpful when we remembered to use it, especially to rule out sneaky sums to 3.

I'm glad you stuck with it and got to the end. I find it incredibly hard to go back to the beginning of a puzzle if I cannot reasonably unwind my mistake. Kudos and thank you for the kind words.
