The world gives a nice vertical element to Kingdom Hearts, even if Sora seems a little slower than normal. The ocean world breaks up the style of gameplay enough to give a new and interesting gameplay. But it seems like people don't like it much, why is that?
Might be cause it’s just so different from the rest of the gameplay, and kinda ignores the progression of your skills a bit. I’m sure KH2’s Atlantica did not help its case, either…
