Fun game with fun mechanics and fun characters. The story won't knock your socks off but I think it nails the emotional beats when it needs to. It also can't be understated how well this Japanese studio nailed the mid 2000s American made anime inspired action cartoon look. BTW don't let the tone of the game fool you. The game can be fairly challenging at parts. I got skill checked a good few times throughout my run of the story on Hard mode. I will mentioned you don't need to be a rhythm game expert to play either. I was scoring B at the best of times and Cs most of the time in that department.
I do think there are a couple of things holding it back. Mostly in the post game. For one the enemy arrangements don't really seem to be effected by difficulty changes like in Bayonetta or DMC. Also, while the big cinematic cutscenes are skippable, there's a lot of small cutscenes that aren't skippable which can get grating when your just trying to play the video game.
