Hrm... first time I saw this, I quit due to crappy controls. Then I got bored and played anyway.
Boring game. Boring 'message'. Boring ending.
And what's 'art' about it?
I'll be the first person to proclaim that I know about as much about art as I do about astrophysics, but I saw very little amounting to 'art' there. Where was it? What was the art?
I'll tell you where videogames can be art: When everything within it is a work of art. When the controls, the gameplay, the story and everything in it turns out to form a singular experience of sight, sound or otherwise appreciated in a more cerebral manner. This wasn't art. This was artsy, and artsy is just someone trying to hard and failing miserably at being 'deep'.
