Good
I'm a little shocked by reviews.
"Expected more gameplay"?! For fuck's sake, JUST READ THE DESCRIPTION!
I personally really liked it. Also, nice touch near the end, the one with "use keyboard to aim".
And to all people saying it would be better as movie: imagine that movie. Really. This was designed with interactivity in mind. And it uses it good.
I rate it in it's genre (art/adventure game), so it gets 9/10.
PS: I just browsed other reviews. There are two sides of good reviews, only this looks bad. So NG crowd isn't totally retarded, it seems.
