Not quite how I wanted it to turn out, but it's sort of playable...

You start by controlling one tank, on one island. Each turn, you can choose to shoot with a tank, colonize another island, or create a new tank. New tanks can only be placed on colonized islands.

The enemy has the same goal. When either you or the computer runs out of tanks, the game is over.

Press space-bar to switch between the 3 turn types (new tank, colonize, shoot). Press tab to cycle through your tanks. WASD or arrow-keys to spin the planet. The text in the game should contain most of the instructions needed.

The source is a horrible mess of spaghetti code that wouldn't happen anywhere other than in a 48-hr game competition ;).
