Space Warz is a simple game reminiscent of Atari's Space Invaders and Air Sea Battle, based on the framework found in Killer Game Programming in Java. The object is simple: hit as many spaceships as you can in 1 minute. You earn 20 points for hitting a fast-moving ship and 10 points for a slow-moving one. Watch out, though, because you can actually obtain a negative score. If a fast-moving spaceship makes it across the terrain, you lose 10 points. If you miss a slow one, you lose 20 points. Don't let the aliens take over Earth!
