Android werewolf(party game) application

We want to create an online application, based on the card game werewolf[1].
The idea is that you as a user can login and join a game of werewolf.
When there's enough players the host will begin the game, and players will be assigned a role (villager, werewolf).
If a player is assigned the role of werewolf, they need to keep it a secret, so that the villager doesn't kill him/her.
When the roles are assigned, the game begins and the players with the role werewolf find a victim (player with role villager), who is then killed and is out of the game. Then the rest of the villagers will try to figure out who the werewolves are...
