This was the first sudoku of which I was actually sad that it was over. I really, really enjoyed this one. Also because I didn't make a single error;) Beautiful setting and nice clues that brought a smile to my face. Thank you very much!

Surprisingly smooth and and tricky at the same time, very well constructed. Thanks!

A really elegant use of LK both for delineating the regions and filling them in. I am not the biggest LK fan - and the use of them here was top notch!

I really enjoyed this puzzle! I got nervous when I saw mathpesto and diagonal sums. These feel like things that would lead me to having to keep lots of numbers in my head, but this was just the right amount of number-crunching for me!

Great !
I had the idea of making a LK Deconstruction a while ago, but I felt it could have turned into an awful lot of painful arithmetic.
Well, you proved me wrong! This has very approchable arithmetic and a lot of interesting deductions along the way. Thanks :)
