Oh nice, I've been into nonograms recently
Would love to see painting (dragging cursor affects multiple tiles in same row or column) and a one button shortcut for marking dead cells (right click would be best)
Edit: Ok after another round it'd be nice to have numbers go grey as you meet their requirements and to not have to fill in dead cells to check my work. Honestly just go check out PictoQuest. It's easy as hell, but it's smooth to play
Edit 2: Ran into a puzzle with multiple solutions, which was weird. I guess that's legal in nonograms? I know it's not for sudoku. All solutions are valid for finishing though
