Any bugs that popped up in my crash reporting are fixed in the latest version, but more importantly, the game now has an ending (for a couple of scenarios, at least)!
If you wipe out all rivals factions, get wiped out, or manage to wipe yourself out (thanks to the person who suggested being able to use Antimatter on yourself), you'll now get some proper closure.
The UI is a bit placeholder for now, and there's no fanfare or post-action report, but it'll do. Things will get flashier and more context sensitive in the near future.
My current priority is fleshing out the faction interactions properly, and then doing proper endings for each scenario. So you could get a domination victory with Eden Corp as your allies, or be content as the pathetic vassal of the Xorg, and everything in-between.
