You probably already seen it but incase you haven't (or for anyone else looking) they posted a public new post to Patreon which had an edit on December 10th which read:
Edit 3 (10 December): Hello again, I'm still alive. And my god, this has been so so difficult to fix. Pretty much everything that could've gone wrong, did go wrong. But lots of troubleshooting and stress later, there finally seems to be light at the end of the tunnel. The only thing that needs to be done is rendering the animations, because they were part of the reason the game was not working. That's gonna take roughly 30 hours, because there's a lot of animations, and my pc is very slow at rendering them. But everything should be good after that. I'm expecting the game to be released in the coming week.
I guess things haven't gone as planned since it has been nearly 2 months since then, would be nice had they said something though.
