It's good that people try new interfaces and escape from the traditional web page layout and he did it, but it lacks some coherence in the usability and navigation.
Interesting way of presenting yourself. However, it is not that innovative as some let us believe, since there are numerous sites who used the city view navigation before. Has a nice rpg game feel to it though.
Yeah, this is nice. I got a bit confused and lost sometimes with the navigation (maybe they should try a perm navitation bar, like the one at http://www.gorillaz.com), but the overall is pretty, pretty good.
