This rules-light storytelling game takes place with two players only. Character creation is relatively free-form and characters are defined by a few narrative tags. After character creation the game proceeds through a series of structured phases with (slightly) different methods used for each phase. In an early phase it is determined (coin flip) that one character ages normally and the other character ages in reverse (become younger at time passes).
The game was published in two versions that vary only by minor formatting.
