This game came out over two years ago on DLSite, hasn't had any updates there in over a year, and the developer has already released a new game since then (and has expressed plans to make another), so I doubt there will be any official content updates for this game. However, someone could implement those unused assets unofficially in a mod.The game outlines the hospital and the evil father file, but neither is complete. This should be the abandoned case the author tweeted
The father who turned into a monster may be a small boss in a hospital setting (Evil father)
Any chance of adding it in the future?
