The Space Base Defender

Our man holding our Controller for our Defense systems is down! We need someone new!
Destroy as many villains, save the planet and get the highest score in the world! Help defend your base from the Rocket Ships attacking. You start off with 10 lives, every time a Rocket Ship hits your base, you lose a live. Every time you let a star hit your base, you gain a live!
Endless waves of upcoming enemies; the longer you survive, the harder it gets!
