Cool puzzle!
Echoing Catalynz's sentiment about the placing digits in fog. Very satisfying.

Thanks for the fun puzzle! I got a little stuck after the break-in but once I got going again it was a nice, smooth solve.

Took way too long for me, not because the ruleset, but because I overdid it with pencil marks and failed to notice a critical hidden single for a good ~30 minutes

Loved the way this ruleset would periodically let me place digits in the middle of a bank of fog -- very satisfying!

I enjoyed this puzzle! I made a lot of mistakes with the negative constraint and the fog, so was grateful the solution was provided to let me know what I was doing wrong. Thank you!

very nice one. I generally like fog puzzles where revealing nothing bears some meaning and this one does that marvelously via the negative constraint.

Nice easy! Took me a few minutes to understand the circle rule. I think its not understood in the rules that a digit cannot be in a cell if there is not a circle there. Very nice puzzle!!
