Very much a 'non-game' in that very little you do has meaningful impact on the game itself, just what you see next in very general decisions. In fact you could say its almost more of an 'interactive experience' then a game per se. But while many might take that as a knock against it, I think it's a perfect use of the medium to convey the game's themes. A really cool short little game. And it's free. So go play it.
