I have mixed feelings on this one. I agree with people who say that the artwork was stunning, and the mood it set was quite nice. But I wanted more in the way of plotline/dialogue. I realize it's a spot the differences game, and those don't normally have a lot, but it would have been nice.
This game is really irritating to me. Its incredibly addicting, and I come back to it about every two hours, when I have more energy, but it's driving me nuts. Once I run out of skill points, it takes me forever to finish a level these days. I haven't gotten to a new city in far too long :(
