Midnight update
I was inactive for longer than I’d have hoped today, but I’ve still made some progress. Anyway, screenshot:

The rough-and-tumble of this is that you’ve got a constant stream of cannon fodder strolling towards the “player” (not you — you’re the, uh, bad guy here, remember?), and you can call in more specialised/powerful “enemies” as the game progresses. As you can see, I’m still hilariously short on content and hilariously awful at art/UI layout.
That’s it for now!
