Asteroid Defense

The humans are coming! Set up a defensive perimeter in the asteroid belt surrounding your planet. It is crucial to contain the threat there, otherwise our entire species will die (you know, humans like to kill everything).

Use WASD or arrow keys to move, left mouse button to shoot.

Most enemies take 3 hits to die. Sometimes, an elite ship will spawn. These ships don't take any damage, but they have a 20 second self-destruct timer, so try your best to delay them.
