No it's not abandoned, yet. Last time I checked (July/August) he was a little burnt out, but still working on the game. He was developing some sort of AI hentai artwork creation thingymabob - he originally drew all the artwork himself which was crazy time consuming, so this was designed to make his updates a bit quicker... lol.
I really want to believe that he is really working in the game and a new update is coming, but reading what he post in discord, and without 0 update for the last couple of years, i'm more in the side to believe that Rannero is the new ICSTOR, only say that he is "finishing" some stuff, or he found some "new bug", or that he is bourn out, but in the reality he is already milking the money that people feed him in patron.
So yeah, this game is really abandoned until he prove the contrary.
Too bad, the game is good, the history of the game was good, the art too, the mecanic, etc., but this is other dev more that he milk the money of the people giving false hope and praying to people for money...
