Holy shit...she said "Let's rock, baby!"

Finished chapter 11. That's it for today. Chapters 9 and 10 were the game's idea of a "recyclefest," sort of recombining bits from all the previous levels, plus making you fight previous bosses again (albeit with a lot less effort needed to win), but thankfully it had enough stuff that was also different so that nothing felt tedious. There was a part several chapters prior where it looked like the game might turn into the ever-dreaded escort mission type for a second, but nope...the character following you doesn't need protection. That could have really fucked the game up!
I think I've only got 3-4 chapters left. Unless something big happens that changes everything, Bayonetta's a 10/10 in my book.
What does the replayability look like at this stage? Are there rewards for multiple play-throughs?
Pretty replayable if you're looking to get achievements and also buy all the moves/accessories/weapons/etc. There's two more difficulty levels to unlock once you finish the game. Doesn't seem like you can get everything in one play-through either, unless you want to grind stages and keep replaying them, but even then I don't know if everything would be available. There's also these optional challenge areas you can find, with certain criteria (such as beating all the enemies with only 10 punch attacks and 10 kick attacks, or never touching the ground) You can replay stages on any difficulty, too. It's also got online leaderboards. Out of all the DMC-style games I have played, this game just fucking trounces them all. It's the game play that does it...tons of combos and moves, plus canceling, plus comboing from one weapon (you can have two equipped at a time) into another...sick, sick stuff. They really outdid themselves. I really should have finished NG Sigma 2 before playing this game, because going back to it is going to feel archaic in comparison. The bar has been raised big time.
Could be bullshit, but I saw a GameFAQs post that said there's a hidden boss that you have to have done a bunch of criteria first to be able to challenge.
