It's a shame because despite the game being a mess (the text being illegible at times and the framerate being about as impressive as a powerpoint presentation) the game really interested back when it came out, hell I actually backed it on patreon for a little while during it's early months but sadly it's been left to rot, which is a shame because the premise and atmosphere was actually pretty good.
From what I understand someone actually took the game removed the sex stuff and made it into a pure horror title, it was released on steam if I recall but it was in Russian so I can't remember the title of it. If it was the originally developer than yeah he probably stepped away from the project and squeezed the last drops of juice by turning it into a actual horror game, if not and someone stole it then ignore most of what i said in this paragraph.
