I'll try to improve the performance, nonetheless :D There are really just a few reasons I keep it in HDRP, and I think I can work around that. Maybe even have it on mobile and HTML. Not gonna go just too much ahead of myself - I'm still just one guy doing almost all the work. We'll see.
The first episode (if nothing too unexpected happens) is set to be done sometime in early 2021 - say January/February. I hope. But, I think I can manage to make the whole game by the end of 2021. Funding will definitely make my life much less miserable, although I'll try to push it through whatsoever.
[SPOILER] One of the endings will be with Cooper up there. Not sure if you'll want it, tho ;)
