Enjoyable, I had a lot of fun time playing it. All the puzzles were smooth play, except the last puzzle, where I thought it froze up a lot and it made it quite difficult to place the squares without a lag, which 15x15, I think there are some nonograms which are bigger, so this might be a stumbling block. The art style is cute, and the sound design is slick and fun to know. I really enjoy nonograms, and I liked how charming their story is while still remaining fun.
