Click your mouse for the initial jump to start the game. Clicking is not required throughout the game. Use your mouse to bump Buster into all of the falling treats. Pumpkins, Candy Corn, Eyeballs and Bags of goodies. Each item will adjust your score numerically, while gathering enough treat bags to spell the words "TRICK OR TREAT" will double your current score. Be careful not to fall to the ground! Once you do, your game will be over, and you will have to start your quest once again.
