New spin on an old game. Design a geometric spaceship and shoot at asteroids. There are powered-up weapons and mysterious status effects to keep it interesting, as well as extra kinds of asteroids that show up as you progress through each wave.
Play by yourself with with a friend (though I'm not sure if one keyboard can handle simultaneous inputs for two users).
See the releases page to download the game. The game runs as a standalone JAR, as it was developed purely using built-in Java graphics and GUI components.
