Starfleet
Asteroid shooter. Control the ship with the arrow keys, and space to fire.
The ship has three systems which can have their levels altered, but you have to use two buttons to change system levels, i.e. pressing "r" to increase shields won't work until you press "d" or "g" to divert energy from engines or weapons respectively.
