Thanks for the comments all around. You raise plenty of valid points that I need to address. I'll get to work on applying some changes, especially to the main menu control. There is one point that I need to talk about though:
-Something has been bothering me for a while. Why do the ships get unselected when we click in space? I can understand when clicking on debris or enemies but, clicking space shouldn't unselect something. It's easy to missclick and it becomes frustrating in times of stress.
This is very interesting. Quite simply, the reason the game acts like that is because Starcraft does, as does pretty much any RTS game with a right-click action interface. To me, clicking on empty space to deselect is an easy way to cancel a selection so that I don't accidentally issue an order to the wrong ship.
This is an issue that all RTS games need to consider, not just mine. The concept behind the left/right click interface is that the left click always does selection and right click performs an action.
I could make left clicking on a ship simply not deselect a ship (there would probably have to be a keyboard shortcut to deselect) but it would be a little strange to players used to this system.
I'm not saying that this is the perfect system, I'm just saying that it's an established system that many RTS games have used and I don't know if I'll actually improve it by changing it. Anyone have any further thoughts on this point?
