Now Bleach has moved to side-scrolling and they did a really good job.
1. difficulty: I though this game was fairly easy, and didn't really have to use my bankai at all in this game.
2. characters: there are only 8 of them(i think), and some of them are bad choices.
3. The game isn't that long and there are a lot of talking parts, luckily you can skip them, but the game doesn't take that long to beat.
my ratings: story: 7/10, I though that the story was okay. It follows rukia finding a sword that controls her and makes her evil, and you have to save her and stop her.
gameplay: 8/10
graphics: 9/10, I thought the graphic were good for a ds game.
sound: 8/10
replay value: 8/10
all in all, if you want a good game that you can just beat up hollows, then this game is for you.
