Thoughts for improvement

The main base has a radius for soaking up debree, that radius usually covers the first mine points close to the base.

Non-visible ships cannot be attacked, although sometimes shots are fired into the darkness since the enemy was visible at the time of firing. Also, sometimes the enemy is just outside of the vision range graphically, but it's still visible. Like when the nose of the ship is tipping outside the fog of war but rest of the ship is in darkness. These situations can make it seem that it's possible for ships to fire into fog of war, but it's not.

All ships and fighters scout and make things visible so that's where the range comes into play.
