Asteroid Field

This Program was written for a contest for the best Java game with a size of no more than 4k, so don't expect any special effects. It's an adaption af the old Asteroids game. You are inside an asteroid field and must destroy the asteroids. The next level starts as soon as you have destroyed all asteroids. The game is over when your space ship smashes into an asteroid. The game features a highscore. You earn one, two or three points for shooting an asteroid, depending on its size.

Steer your space ship with the left, right and up cursor keys. Press space to shoot. Any other key restarts the game. Alt+F4 ends the game.
