I've added a new devlog post here with some tips to help folks who might be getting stuck at various points in the game. It has spoilers though, so keep that in mind before checking it out.

I'd rather folks know what to do to progress than give up in frustration. If there's something I didn't cover in the tips article and you need more specific help, please reach out via comments and I'll assist.
