Dear Deliverance (2014)

User summary: The game is played as a series of Twitter exchanges ("tweets") between two players. Any number of people may watch the game, but only the two players may contribute. The rules put forward a method of creating the scenario and then playing it out via back-and-forth narrative (necessarily short). Although the game specifically is intended for Twitter, the mechanics are simple enough that it could readily be adapted to, essentially, any form of relatively anonymous, non-verbal communication.
