It really is just a better Sticker Star.
Keep in mind what I just said though, Sticker Star, meaning it plays exactly the same and has the same exact shitty battle system that was bad in that game that's bad in here. They're both structured the exact same way and there's still little to no reason to fight in this game. The paint hammers seem like a reason but they don't mean anything when its so easy to get paint in this game.
Man the only thing I realized with this replay is that the ost is one of the best in the series, really catchy tunes and a lot of generally amazing tracks. Other than that though... my opinions haven't changed, if anything, they got a little worse.
I don't ever want to replay this one again.
