All puzzles solved on maximum difficulty; all achievements unlocked. Picross is always an addictively compelling type of puzzle game, but this is one of the best implementations that I've played in a long time. This is a charmingly well-presented package with a nice theme around an art gallery setting, and boasting some subtle but really appreciated (optional) quality of life features, such as aiding drawing long straight lines with some auto-correction of mouse inputs. Of course, the puzzles themselves are really the most important part of the package and these live up to the quality of the rest of the game, all being possible to solve without guessing and with some impressive variety and imagination in their subject.
