Succubus Research Diary is now (properly) available on itch.io. The actual release date was 23th of October, but for reasons mysterious to me, it took a while before it was indexed (i.e., started showing up in Search and Browse). Perhaps it's a busy time of the year?

Now then, the game page mentions the upcoming final update that will complete the afterstory. I've put my newest project on hold and started working on the update in earnest, so there's a good chance that it will be ready by early December. The update will focus on the new character, Julie, who might just be up to something naughty... *Ahem*... Well, but I'd better not say anything too spoiler-ish at this point. Stay tuned for the next update!
