Here is an overview of the game, via its Steam page:

During an expedition to the Moon, two astronauts find themselves in a familiar town back on Earth. They soon discover the town is the beginning of a strange and mysterious journey…

Lifeless Moon is a spiritual successor to our previous title Lifeless Planet. Featuring support for virtual reality (but playable without!), Lifeless Moon takes players on a fantastic journey through the eyes of Apollo-era astronauts. There will be light platforming and a deeper focus on puzzles than in Lifeless Planet. The core gameplay experience is one of exploration and discovery, complementing the mysterious and psychological themes of the story.
