I simply cannot call this a game, it is an experience, you just have to play it yourself. Give yourself an hour and a half alone to sit down with zero distractions to listen and observe. http://store.steampowered.com/app/303210/ Also, don't watch the trailer or read reviews, basically go play this having zero knowledge about it.
Ah yes, I've heard of this game. Heard of debates and podcasts if this is a true story or not. Not gonna spoil anything, but, it's from the dude that made 'The Stanley Parable'.
Yeah that's how I found the game, I loved "The Stanley Parable", I hope the story is true, it sounds like it is but just that the narration is a bit over-dramatic at times. regardless of whether it is or not it's still a great story. I can relate to this as I have a huge folder full of unfinished games/maps on the source engine and I used to suffer from social anxiety.
