Alice is Missing

From the kickstarter:

Alice is Missing, a silent role-playing game about the disappearance of Alice Briarwood, a high school junior in the small town of Silent Falls.
...
The game is played live and without verbal communication. Players inhabit their character for the entirety of the 90-minute play session, and instead of speaking, send text messages back and forth to the other characters in a group chat, as well as individually, as though they aren’t in the same place together.

Alice is Missing is a silent role playing game about the disappearance of Alice Briarwood, a high school junior in the sleepy Northern California town of Silent Falls. During the game, players use their phones to send text messages to each other as they unearth clues about what happened to Alice.

The game runs over a single session of two or three hours. There is no formal game master, but one player will need to explain and facilitate the rules. In the first 45 minutes, players create their characters, their relationships to Alice, and their ties with each other. The next 90 minutes follow the characters’ text message conversations as they uncover Alice’s fate.
