Bayonetta however you wish, but there's only one definitive authority on the game: director Hideki Kamiya. Because people were uploading so many commentary and walkthrough videos, Kamiya thought he'd offer his own.
So over the course of the next however long it takes, Kamiya will be replaying the entire game, offering his own insights and anecdotes from the game's developments on the Platinum Games blog. Honestly, we can't wait to hear what he has to say about that whole "masturbating angel" scene.
You'll find the first two videos just past the jump.
