The object of Defend Your Castle is to keep the stick people from swarming your castle and tearing it down. You do this by grabbing them with the mouse and then dropping them from obscene heights so that they splatter all over the grass. Bloody I know! The game is played in stages and in between you will have the opportunity to buy upgrades for your castle (see below). Each stage gets progressively more difficult. See how far you can get!
