Use the left and right arrow keys to move the chocolate sauce bottle. Shoot all 5 apples to win. Beware, you only have 7 bullets. Press space to shoot. This IS designed to be a little slow like the arcade game. You may need to wait a few seconds for the winning backdrop to appear.
Chocolate invaders is based on Space invaders, which was developed by Tomohiro Nishikado. Without him and his amazing idea, this game wouldn't be here!
