After 2 chapters (one of which I've tackled at 9.0 intensity; fun times) and a handful of online battles(I was wrecking with the Somewhat Staff), I'm very pleased with the game. Thankfully, my worries about the volume of the voice recording has been laid to rest! Everything sounds perfect. I love the fourth-wall-irreverent dialogue.
I will concede that the controls are a bit of a chore to get comfortable with, but with every other aspect of the game poised and polished and gleaming with charm, it's not a dealbreaker. Definitely a welcome edition to the growing list of high quality 3DS retail games. I love this system.
