Very tough puzzle in my view. Had to let it "rest" several times.
Still, a very rewarding solve experience! Thanks a lot :-)

It's great to find out that you got over the line with satisfaction. Thanks for persevering to find the logic! :-)

Thank you all for giving it a go and I'm pleased most of you all enjoyed the logical solve path :-) My earlier version had a potential logical bypass so I'm grateful to the Discord testers for spotting it. The number of black dots are kept down to a minimum to make the next step visually clearer whilst making the negative constraint play a key role later on.

This was really hard to wrap my head around, but forgetting the negative constraint was what held me back the most I think, loved to color this one to help find the solution as well, ty for making this!

I also found the break-in really amusing and not too hard to spot, but the rest of the puzzle was tricky as hell (for me at least). Thanks for making it.

That opening logic made me smile and I enjoyed using the negative constraint. Superb!

Spectacular puzzle! The opening was beautiful and the path afterwards got quite tricky till the big breakthrough, and I was jawdropping at that point. Thank you for this journey ;)

What a beautiful creation! I loved this even though I completely forgot the negative constraint for idk 40 minutes. The idea is splendid and the execution is on point!
