Oh boy, here we go again.
It's actually in Unreal 5.
Game is still on development, consider it as "alpha version", or "test version"... Or WIP even.
Basically, game is for PC/VR(that explains why are you getting erorrs), but in lastest version, I think, they're making PC first, then VR... I'm not a dev, lol.
In "Vs. Titan mode" it can be with VR, but in other mode - no.
Althrough, in early version (0.19 and early, I think? Basically, check gumroad) there is main mode. Which is just a concept(WIP)... But it has VR.
In version 0.24 - it has sex scenes. But for 0.24 it needs to subscribe for $10 in SStar to get 0.24.
TL;DR: game is not ready, it's WIP, game was originally made in Unreal4, now in Unreal5. There was PC/VR, now PC, they still making it to VR, definitely in later versions. I don't have 0.24, so I don't know if there's VR available that doesn't have in 0.23. Also you all can try to command to make something in console (key button is `). Sadly, I don't know about Unreal engine anything, so I didn't tired everything other than free camera, lol.
By the way...
Bob69, a tab in first post "Key Settings" is actually old (I think it's from 0.14?), and useful only in "Vs. Titan mode", so better if you write on top of settings that those settings was made for "Vs. Titan mode".
Other than, I'm looking for this game as well, even though I'm not into giant/macro kink, lol.
Artspam(who is dev) doesn't have any schedule to post new versions, but you all can look at his twitter... I mean, X (
/ks/ or
/gz/, lol) to check any updates, as well in Furaffinity, Artspam sometimes remembers and posts there a new public version.
