The art is first thing you see here, obviously. And it's... Not the worst combination of CGI and drawn art, but you definitely need a moment to get used to it and even after that some frames look atrocious. But some do look pretty decent. I think lighting is what matters here.
The story, though... Well, if it was an anime (like an OVA) - too underdeveloped, although the concept is pretty interesting. But since it's a trailer... I guess it is ok, since it does cover main points of the concept here. Too bad it's not my type of game, otherwise I'd try it for the story.
