Mr. Turret shoots down airborne threats to our way of life!
Use the up and down arrows to aim, [space] to fire. Hold [shift] while aiming to increase turning speed. You have a limited number of shots. Run out without downing all targets and you'll lose a life. Let one of the targets cross the border and you'll lose a life. At the beginning of each stage, you're awarded a set amount of shots (par) to clear the level. Your unused shots carry over to the stage.
