Play a game of Kat Kards by Professor Co! You can customize the color of the helper and the background, then click the instructions and play! There's more instructions in-game, but basically: Click one of the two cards on the bottom. If your card is higher than the one your opponent picks, their life will lower. If your card is lower, your life will lower. Your alltime wins and losses save. ((Adding fighting your friends when I get around to it, It'll be fun))
