A good game, but not as good as the first one
The main problem of the game is that is too damn easy. I mean, I can easily beat the game just pressing X and / all the way till the end, with exceptions of some bosses, there's no strategy at all in the battles, just button-mashing. Sometimes you feel like the enemies aren't even trying to kill you. And the worlds are too linear, no secret passages, hidden treasure or anything, a real downgrade in comparision to the first game.
The story is another problem. There's a new enemy called Organization XIII, their main purpose is to collect hearts and become human again, one thing I don't understand is why do we have to fight them? Well, whatever. Another thing I don't understand is why we have to revisit all those Disney worlds. In KH1 we visited each world to seal the keyhole in order to prevent darkness to take over that world. In this game, we open the keyholes in order to open passage to others Disneys worlds, so doesnt makes much sense at all.
Anyway, this game is still good. Honestly, it can be really fun to wipe the floor if heartless sometimes when you are bored. But the first is far better imo
