I don't want to write a summary here.
The gameplay was way to slow, just as the controls, you should be able to send units trough clicking on the minimap. Also, add a goddamn queue, the ability to create more motherships, something. I'm not sure if they do, but the asteroids will never run out of ore? (I'm not quite sure), but with that there would definitely be alow more fighting for map control.
I'd suggest you'd increase gamespeed as that would really help a lot.
It's cool that you created an rts, I'm currently doing the same thing xD
Looking forward to the multiplayer (definitely a must do).
