It’s going to be an arena shooter of some kind, with the aim of staying alive but getting the minimal score (*avoiding* power-ups, collectibles, and bonuses?). Perhaps a score that ticks downwards over time, if you can avoid killing/collecting things?

But for now, I’ve at least got basic player movement and done the mouse-to-world logic for firing. And spent too long messing with SpaceScape to create a skybox…
