This is a pretty middle of the road nonogram game. The puzzles are never particularly challenging, so no need for more advanced techniques. The auto-correction and scoring system can be irritating given how easy it is to fat finger a square unintentionally. Losing out on a perfect rating for a puzzle is frustrating when a touch isn't registered where you expect. The game also lacks some of the conveniences of other modern nonogram games, such as greyed numbers when they've been solved for a row or column. The majority of the puzzles also aren't even actually themed around Hatsune Miku, it's not until the special puzzles that they're themed, and these puzzles are poorly designed, not even matching the shapes of the characters they're supposed to be. This one was definitely a disappointment, especially coming off of Konami's excellent Pixel Puzzle Collection.
