From what I can tell (not having played the game), this is simply just a pile of crap prototype selling for a wild price that people seem to be buying due to the pure fact that they think it's "art" because it's short and simple. Maybe they only like it because they think they can see through it, know the real meaning to it and that anyone that dislikes the game is a "brain-dead fool that doesn't understand art". Am I right? I think I am.
"It's not a game, it's an experience." Really? Keep on telling yourself that because from what I can tell it's really not, so stop thinking you're some sort of master race that thinks a game's good because it's short and crap.
Call me heartless or whatever you want to call me, because if something else triggered in my mind when I first heard of this game, I may have bought it and really enjoyed it. But you know what? I didn't. It's as simple as that.
I bet I could make a better game idea in seconds. You know what? I will.
< that's a cage. You play as a guy that's in it. You finally get out one day. You venture outside, you do some other meaningless crap and in the middle of that find photos of your family. The game ends. You're free.
And there you have it, a 59 year old male's opinion on this piece of muck and the players that think they have some sort of advanced mind set and a high IQ because they "understand" it.
tl;dr: Short, meaningless and stupid does not mean art. It means you're getting money taken from you. 'Ya done goofed.
