I recently got into nonograms/picross, it's a cool novel idea, and any game where you play as a frog is cute. The difficulty does seem to vary a lot, one level might require using a combination of picross hints and minesweeper hints and take a while, and the next might have a path of "zero" mine tiles from the start to the goal, so it doesn't require any puzzling at all. looking forward to seeing what's added in the future!
