A pretty good game but with flaws.
Recomendations.
AI : Have it attack the nearest hostile target first. They seem to randomly fire sometimes and they will take fire off enemy vessels to fire on the enemy miners which doesn't really seem to affect how many ships or how much money the enemy has anyways.
Hotkeys: Make hitting space bar bring up all turrets and thier areas of influence in blue. The blue would allow you to see the all turrets life and be able to upgrade/fix/increase health BUT would not move them. I don't know how many times i had clicked on multiple turrets so i could keep track of thier health, only to have them all move to a single point because i accidently clicked somewhere.
Also allow a second space bar click to automatically unselect any menu, or selected turrets whether green, blue or the space station.
Also make 1,2,3,4 hotkeys for quick building the corresponding items.
Movement: This needs some work. The turrets many times refused to move where i told them to go ESPECIALLY around the space station.
Repair for station: Even if it costs a lot, i'd like the option to do it.
Limit the distance of turret/enemyship fire: My station got the crap kicked out of it from ships that weren't even on the screen yet.
All in all, a pretty good game. Just needs some tweeks.
