Power Power: The Werecat Card Battle

A card game where you try to raise your catgirl (a girl with cat-like features, such as cat-ears and a tail) from a kitten to an adult before the other players do so with their own catgirl. A version 2.00 was released with a new set of cards and new rules (not just 'errata' fixes or minor tweaks, but a reworking).
