Betting
If you died N1 or N2, you can bet on an alignment with Town Points. If that alignment wins, you get double the money, and if they lose, you lose the money.
Possessing Pets
If you are dead, you can choose to possess a pet. The owner will be notified, with this message: "As you wake up, you notice your pet looks off a bit." If you attempt to talk, it would just come out as something like this:
[Player's Name]'s Kickstarter Fairy: *Flap, Flap!*
[Player's Name]'s Snowman: *Twinkle!*
Spectating
You can choose to spectate the game. If you do this, you can see anyone's Last Will and Death Note, what they do at night (And for Jailor, see what they choose during the day.), and what they say. However, you can not be revived, talk with medium, or even become a normal dead person again. Like the pet, the whole town will be notified of this: "While doing your jobs, you feel like you are being watched by an outside force!"
And something I'm on the fence about is filling in. If the person a retributionists is reviving has left, a dead person can volunteer to "fill in" for them. They know everything their role said and did, and their Last Wills and Death Notes. Once again, the entire town will be notified of this: "X was revived by a Retributionist, however his eyes look a bit like Y's." But then, if a role who knew a lot before dieing filled in... Maybe only allow the roles who can't get info on their own, like Amnesiac (Before deciding), Survivor, Witch, Serial Killer, Arso, etc?
