I'm really enjoying Otogi 2 so far. At this point I have a good feeling for the gameplay, but in the beginning I was getting beat down badly by some of the levels. I haven't really played a game like this before; I love the wide-open feel to the movement. All of the characters but one has a double jump. One of them (Suetake) even has the ability to jump infinitely many times, allowing completelely unrestricted exploration of the worlds. The other characters move so effortlessly that the freedom is almost as complete no matter who you choose.
The action is also pretty exciting, with good variation on the levels so far (although when you really get down to it, each level is about destroying things). I don't know how long the gameplay will stay fresh-time will tell- but the game is certainly beautiful to look at and listen to.
