played a lot of your puzzles lately and thus this wasn't difficult at all for me;
the one thing I struggled with was finding the what to colour in first but that was a minute or two until I realized the one cell that sticks out.
after that all simple colouring very nice endgame btw (something I do not enjoy usually...)

I loved this one! I forgot about the negative constraint at first, which made it seem impossible, but then I reviewed the rules and figured it out pretty quickly!

Sublime puzzle! As this was my first connected x-lines puzzle, it needed some thinking about how to approach this. I had a fun time finding out and solving this. Thank you
