I will say it was a game that I had really looked forward to, but I lost interest in it fairly quickly.
By objective measure it seems like a generally good, well-received game, but I think the gameplay just didn't interest me after the first few hours. It did a good job selling itself on its art style, but the substance was just a bit lacking, in my opinion.
Maybe I've just played too many JRPGs in my time that I felt it wasn't really doing anything novel.
