Click the green flag, and then the space bar to start. Use right and left arrow keys to move the Millenium Falcon. Press the "X" key to shoot lasers. If a sprite makes a blow up sound but it doesn't blow up, you have hit it but not destroyed it. The TIE Fighters will turn to ghosts when you destroy them and continue to shoot lasers at you, just wanted to make it a bit harder.
