I think about this game every day and I finished it months ago! A masterpiece. Beautifully done, with an incredible psychological pull. Do yourself a favor, skip the trailer and just go straight in like I did.
For the best experience you’ll need headphones, in a dark room. Avoid getting the iphone version if you can (still great though).
The ending was shocking in its way and I understand how confused some people are by the uncoventional nature of it—the more you think about the ending, and what has happened throughout the experience, the richer it gets and it is actually a very fulfilling experience. It is perfect. Bravo to the devs.
