I’m personally aiming for “Zork, but in space and red”, and have spent most of my time thus far trying to make it look all fancy and make the keyword highlighting work properly.
I’m making it in Unity 2021 w/ HDRP, if only because it makes adding bloom and assorted post-processing tiddlywinks trivial, and I think that the weird phosphor-delay-y effect caused by the fancy anti-aliasing that I accidentally left on looked pretty cool.
As for “plot” or “theme” (silly things), the game takes place on a space station controlled by an aging biological processor after most of the crew was killed by a virus or whatever. I haven’t quite gotten it down yet. Just the whole “brain space station” thing, really.
Happy debugging! here is a silly screenshot featuring balls
