8-Bit Werewolf / Mafia Mini Playing Cards

I really like that these decks are small enough to fit in your pocket to take to a party but there are some roles that I don't understand what they do, specifically with the Mafia cards. I tried to get a hold of Home Run Games and they were not helpful.

you get two tiny decks for the price of one! these seem like d and d meets among us. each card has a power. go find yours!
