This is a very line-drawn game made completely from actionscript in an external ActionScript file. All animation and drawing was handled in that external file and included in the .fla that produced the .swf file at compile (publish) time. Use the mouse to aim. Clicking fires a missle; the longer you hold down the mouse the more powerful the shot. Hold down too long, however, and your missle will fire automatically. You can also use the arrow keys to move around.
