This game was made by two people. TWO. It’s a first person game without the shooting; you awaken on an island, and you’re sick.
Through exploration, foraging, and analysis, you must find a cure for your illness. The game doesn’t give you any of the usual superhuman skills you are used to. You cannot sprint endlessly and leap to great heights. Sliding down a slope can lead to falling, which can lead to death. Your map does not automagically update; triangulation relative to known landmarks is necessary.
The island is mysterious, and its environments are diverse and interesting. And yes, the game doesn’t have AAA polish, but it was made by two people. Quite remarkable.
