Halley's Comet
 
 
 Useful hints:
 In the game, each level consists of two parts. 
 In the first part, you fly in space. In the second 
 part you are, what appears, inside a spaceship. At 
 the end of this part, there is a "level boss" 
 consisting of flashing squares that fires at you. 
 Shoot all but one of these squares and then press 
 the hyperspace button (the smartbomb) when the final 
 square is lit. You should now recieve 1 000 000 points! 
 As far as I know, this works for all level bosses.
 
 Another tip: When the game is in Game Over mode, you 
 can actually control the ship at one point. This is 
 rather useless, but fun!
