WOW. This game was a great experience. It took me around an hour or two to complete. Its very linear and story driven. The story is absolutely realistic. This isn't as extreme as something like the game Outcast. It's chilling due to the realism, and the progression is great. Some parts were very unnerving, but there are no jump scares or even other people/creatures to interact with. You're alone. Exploring. Uncovering the truth. Some parts were a bit hard to figure out, like others mentioned though (the padlock code!).
