Space Bacon: When Pigs Fly

Aliens that look just like pigs are attacking the moon! Your job: Protect the moon from the evil alien pigs. Right now, collision checking is on, but there's infinite lives for testing purposes. You can also shoot the pigs now and get a point for each one you shoot. Right now, it's set up so when your ship touches a pig, you lose a life. In a way, it's similar to the game 'Space Jockey', because I played that for hours trying to get a good score in the High Score Club, thinking, "This might be able to do in Batari BASIC."
