Pretty sure the game is done from a story perspective, but the dev mentioned that he had plans to go back and remaster some of the earlier content. I believe the game is feature-complete, if that's what you're wondering about.
Yeah, the story is complete, but the Final release will be a cleanup of code, reshooting some scenes, some minor additional content, and extras, like Chapter select and Outtakes. And the ability to unlock all scenes in the gallery.
