Ever since the Dev has posted that roadmap, he's been blitzing through it. From what I know with the help of "GoogleTranslate" he has 1 more character to work on the cycled character immersion activities (like reading books etc).
His "employed help" is adding the clothing for the big animations for him, and not only that but he talked about Hot springs with the Sub-Heroines.
He wants it to be satisfying with them wearing unique clothes, kinda unsure if we even gettin the game in February tbh, since he gets these great ideas then works diligently on them.
(At least we're promised a treasure of a hentai game and those talented modders will keep us busy for quite some time on it too.)
