As you can see, I've decided to go a slightly different route with the theme. The original idea was for it to be a sort of techno-fantasy cross all the way through; but fiddling with the game recently has given me a few alternate ideas.
Basically, now it's going to jump back and forth between different settings, this way I can cover more familiar bases (ie. bio horror ala R-Type) as well go back to some older ideas I'd like to re-use. Every one will have a playable ship to match it, too. :)
