Little Bugs and some ideas
The bugs first:
1. When I dock, open the store and select Weapons-section, close the store, and open it again, the chooser shows the Weapons section, but the stuff are from armoury section. Small bug, eh?
2. There's an asteroid half way to the end of zone(leftside of the big ship), that shows as a red dot in radar. It is shown even if I am on the right side of the big ship.
(3.) If the second one wasn't bug, then this is: no else of the asteroids are shown in the radar.
Then some things to do better:
1. The background could be multilayered, look here to see how.
2. Do some wingmans able to hire. They should take something like 30% of looted money.
The basic idea was great.
Have fun! :)
