Thanks, I hadn't coded for a while so I really got into it.
My computer is really slow so now I'm trying to find ways to keep the FPS respectable when lots of ships are built.
A problem I noticed about the AI is when you destroy one of their planets they continue to try to defend it. I don't if that's because of something I changed or not.
Updates:
* New subroutine checks if the current selection is still valid (i.e. if you can still see enemy ships you've selected etc)
* Stars are drawn to an off-screen bitmap before the main loop and copied to screen each cycle. Allows for more a complex background while actually gaining a few FPS.

Ideas:
* Multiple enemies: maybe have all four races competing against each other? I haven't gotten the gist of the AI yet so if you are still working on it that would be a cool thing to add.
* Display game time.
* Store and display number of kills by each ship. Taking it further ships could have a rank (private, lieutenant) associated with the ship's kills.
* Option to build planetary defences.
* Low-res generated graphics. I've made some that I might use but it's not a priority. I mainly want to do this so I could write the images to a memblock which would increase FPS for my old machine lol.
