Demon StarPC Port

Your starship crosses a universe of nebulae, spiral galaxies, stars and double spiral galaxies, worth 5, 10, 15 and 20 energy units. Shoot them with matter conversion torpedoes to take their energy, but never fly into one. A Quasar arrives with a deep warning: destroy it in about 12 seconds for 100 units, or lose 500. Now and then a Demon Star comes instead, in a blinding flash with a roar. It shortens your torpedoes' range, and failing to destroy it in time costs your ship; it is worth 500. Every 1000 units brings 100 more and a new universe, and past 3000 the universe grows denser. The ship and torpedoes wrap around the edges. Running out of energy also ends the game.

Controls: Use either joystick. The stick flies the ship in eight directions, and it keeps going the way it last went; the button fires, and held, fires again and again. The keypad is not used.
