Kat Game

A cute question game for my kjæreste. In this game, two players ask each other questions or present physical challenges to each other, similar to truth or dare. There are additionally sub-games within this that offer their own challenges and rules. This game will not repeat cards until all cards have been played through, and skipping a card is as easy as clicking on it~
