Use the arrow keys to move the camera around, thus aiming to hit the ships. Use the space key to fire.
I am proud of this, as it's my first pen-only project. Feel free to use the game engine for whatever you find fitting. It is currently incomplete in the following respects: • Ships don't disappear • Shots don't explode • Ships don't regenerate once there are none left. (This is solely because of their disappearance issue, so I can fix this point myself, although ideas would be appreciated). • No title, (I can also fix this myself, but again, ideas would be appreciated).
