Another important component to Layton's overall feel is the gorgeous, hand-drawn art, in a very European style and color scheme. Game|Life's update includes drawings of some of the game's environments in a much-better-than-DS resolution. There's a reason that Professor Layton is a constant bestseller in Japan, and this art ... probably isn't it, but it doesn't hurt. It's really very nice to have something pretty to look at while you're dying of puzzle-solving failure.
