Well worth the year and a half of maturation! Opening is beautifully crafted and the remaining clues bring the whole thing to a satisfying conclusion. Thanks :)

Wow! It's rare that a variant sudoku impresses me nowadays, but this one did.

Very nice construction, some digits almost dancing into place (even though that makes it sound easier than it was). Thanks!

Absolutely fascinating! I think the amazing break-in was the original idea, but the rest of the setting isn’t less admirable. Thank you very much for creating and sharing this fantastic puzzle.

Beautiful puzzle. Delightfully clever break-in and super smooth after that.

Frankly still not quite sure what the idea was that led to this puzzle, but I did enjoy solving it. Never easy, but always some place to chip away at options until you find a new limitation.
