This makes no sense, I saw it already 3 or even 4 years ago on Steam. Maybe it was not finished but it definetly left the Beta Phase... Also please note that I am not able to look up the steam page myself anymore, as germany is blocked from it.

I found out more after making this post.
As it stands now this particular game is abandoned. he is currently focussing on severl prequal dating sims style game and he SPECIFICALLY stated they will NOT be hentai games. He said there might be some level of nudity, but nothing like it is seen here.
he wants to focus completely on the story arc, and when he gets caught back up to this point in the storyline i believe he is going to make a whole new game to cover the events from this one.
kinda sad because I was really enjoying how this game was playing out.
