Another one of those "let's shove every novelty PS Vita gimmick into this whether that makes sense or not" games
Mechanically, it's too simple, sometimes naive. Combat consists of one button, no lock-on or auto-aim. The ability to fly is pretty cool, but in practice doesn't serve any gameplay purpose other than faster movement.
Since it's an open-world game, there's an urge to explore, but you're not allowed to go to any interesting places.
Really the main and only attraction of this game is the presentation. I'm not particularly into the whole Amelie meets Ghibli aesthetic, but I loved the music. And I think the animations are really smooth and make actions more enjoyable to perform.
This, sadly, doesn't save the game from being boring. An absolutely atrocious tutorial is followed by mind-numbingly basic missions. The story is anime-quality, thus unable to hold my attention either. The main protagonist keeps talking to her cat like an insane person.
