This is the most pi.fyi-core game. You are a post-apocalyptic mailman with a baby that can see ghosts, who wanders a quiet landscape of moss and rock to bring scattered and isolated people things like cd's, sheet music, robot parts, energy drinks, medicine, and a million odd little items.
You quickly find yourself in a rhythm, walking, using ropes and ladders to cross difficult terrain, and suddenly that rhythm is interrupted by ghost whales, lions, and violence that is literally transporting. It's incredibly cryptic but as you form connections between survivors it all begins to make sense.
