Read on your own risk, but I try to be as vague as possible. And I think I am not spoiling a lot, because you will learn about it in the first few minutes of the game: You are trapped in a time loop and try to find out why it is happening and who caused it. You will follow clues that lead you through the whole star system where you will visit strange worlds and try to solve the riddle, each new time loop getting close to the solution. The riddles/mysteries are really great and integrate fantastically in the world.

I would like to describe it as the perfect mixture of death loop and Myst.
