I have been playing this game for about an hour or so and I must say, I fell in love with the game. The art style is beautiful, the story is interesting, and the controls are perfect. I died a couple of times on normal difficulty but thats just part of the fun, right? The only thing that bothers me is that there is a "completion" bar in the menu (I think thats what it says, all I know is it has to do with completion) and after playing for that while its more than half way through. I thought maybe the game would be longer. Other than that, the game runs fine on my 4s, controls are perfect, and I recommend this game!
