Use the left and right arrow keys to move left and right... what else did you expect? Shields is practically health. Tie fighters you can shoot and get points, but Star Destroyers and Death Stars you cannot destroy. Yodas multiply the amount of points you get for hitting a Tie fighter. 1000 points to advance to the next level. Click X to switch to X mode. Fyi, for the first few levels, you might want to set your brightness to 100% because it's slightly difficult to see the Tie-fighters in the darkness of hyperspace.
I tried to edit this so it looks starwars like. Each level is supposed to look like you were flying by a different planet with the exception of the first two levels. Thank you to upbeat music productions for the music in this game and of course, thank you to John Williams for being the talented musician who wrote the songs we all know and love. http://upbeatmusicproductions.com/_UpBeatPractice/index.php?path=StarWars/
