Very good.
Story: The game is about a kid named Sora who has probably played Final Fantasy VII, because he has ridiculous, spiky hair. It starts as you collect supplies for your raft so you can ditch the island that you live on. But the night before you leave, some strange shadowy creatures known as Heartless that eat people's hearts. Your friend Riku is abducted by shadowy thingies and you recieve a giant key that you can kill things with. 9.5/10
Graphics: The graphics are really good. The world is very detailed, but there are a few glitches here and there. Otherwise, the motion captured cutscenes are pretty good! 8.5/10
Controls: The controls are kind of different from what you may have played. The right analog stick is used to navigate through the submenu on the bottom-left corner of the screen. The camera doesn't work very well, though. Sometimes the camera doesn't want to cooperate. 8.5/10
Difficulty: The difficulty can be sort of aggrivating. I'm so stupid! I started my first game on expert mode! Yet, I still made it through, somehow. Until you have beaten the game on normal mode, don't jump right into expert mode. It is a pain in the butt. 9/10
Overall, it's a pretty good game. It has a few flaws here and there, but otherwise, it's pretty good! 9/10
