The Loss (2013)

From the introduction:

The Loss explores sorrow, what it means to lose oneself, and the losses that cut you in ways that words cannot describe. It also examines how to move through sorrow to the other side. The narrative permits the unsaid to remain unsaid, and plays out largely in the players’ heads, while the underlying physical game mechanics help the game to put real weight on the players’ shoulders, since sometimes emotional pain feels like a punch to the gut.
