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!
