After you set difficulty level, click "Start" to start playing. Control your crazy fly with arrow keys. You can fire with "Space" key, "Ctrl" key to spit out. But you should use big spit at the end of the each chapter when you see the big monsters. Because you have limited spits. If you hold the up key, your fly saves position in the the sky for a while. You can use this when you are passing the long areas. You gain points on each picked gook. Have fun. (:
