A game about fear of the unknown. A year ago, the Moon was sent violently flying off course by a catastrophic explosion, depriving Earth of its steady stream of resources. Less importantly, the two maintenance workers on there when the explosion occurred have been stranded ever since. It's not so bad, honestly. The Heart provides for everything, a practically infinite source that gives them water, food, and powers their satellite as they wait with ever dwindling hopes for rescue. Really, it's boring, but there's no reason to stress out so long as- The Heart has stopped.
