Re: development process - Chapter 3 is only a couple of weeks from release. As far as everything else goes, I prefer not to talk too much about future plans at this time - though I will confirm that multiple endings are planned - and at this time pregnancy is not planned as a major plotline. (I won't rule out including it entirely as sometimes plans do change - but if it was included, it would be minor and not a major focus of the story)
My patreon page posts weekly updates for subscribers - as well as public posts whenever I have release info to announce. One such post was put up just a few hours ago - so if you don't want to subscribe but want to be notified of release info, feel free to follow the page (Or my twitter - @cskingames). Other than that I'll always post a small dev blog on release day here on itch.
