Use your mouse to sight an approaching ship in your cross-hairs. A target box lights up when an enemy ship is in your sights,
giving the craft's closing speed and range. Click the left mouse button to fire (you have unlimited ammo--fire a lot!).
Whenever an enemy fighter gets past you, it will fire on your ship. You will see the screen flash and shake if they score a hit.
Watch your shields - when they go, so do you.
Pause the game at any time by hitting the 'P' key. Hit again to resume. Use the 'M' key to toggle sound on and off.
Turning off the sound effects ('M' key) may increase game speed.
