The game is not abandoned, Ocean communicates continuously with the Patreons and not only that, I am not yet a patreon but I am updated thanks to Discord. The game is currently being reworked, it happens when you participate in Beta tests, because that's what these games are. Ocean explained that the next releases will be closer because he has increased the power of his computer and because he is studying a better way to work on 2 games at the same time. Summer's Gone also changed the writer during the work, Ocean had entrusted the work to a colleague, but after the first release he pulled back, Ocean then decided to continue him and now he is also rewriting the parts made by his predecessor , so it took longer.
This also explains the horror tag in my opinion, if you remember at the beginning of the story the MC can decide to shoot a woman, and also speaks as a possessed, defining the woman as a "miserable human", probably Regium, I think the first was called that. author, he wanted to include horror and supernatural elements, but then Ocean took over and I think he doesn't share that vision.
