So, i'm a part of their Discord. This game is basically a one and done situation (with a couple minor content updates), this was created YEARS ago. What the creator originally planned on doing was making a longer game, but retracted and instead decided that they wanted to make smaller games, piece by piece to tell the story. So hopefully all the things i'm about to say answer all your questions, though sadly I can't remember the discord location to send you the link.
So, are they making a new game? Supposedly yes.
Is there any updates on what we may/may not get? Barely any at all. To be honest, I want to say no.
Is this game or any future game by this developer likely to come out? I would say... maybe a 10% chance? And that's me being generous.
There's no guarantee. Currently, the Discord hasn't really posted any true updates for this game since like 2023. Though the community behind it have a ton of faith that this game will one day to get an ending or a sequel, or maybe even updates. As of right now though... it's not looking likely. The last "update" for the game was for a sick dog they wanted donations for and even that was all the way back in 2024. After that, it's been radio silence. Even the real last "update" on the game was them telling us their episodic plan for his series, but nothing has been shown and even that was in January 2024. Not even screen caps of models to show proof of life or showing any kind of effort being put towards a new project.
It's kind of a running joke to say that the creator is still actively working on it in their Discord. Basically, if you ask about any updates at all or any information about ANY projects at all, you just get shut down or told to "let him cook" pretty much lol.
I should mention, it's also hard to say really how much was actually finished. He shut down the Patreon and seems to go on hiatus from to time. Even to a point where the mods seem to occasionally get confused as to what's going on. As you can see in the comments, there's a few people being HIGHLY supportive of what he's doing, but i'm going to be honest, the way they respond is highly similar to the mods in the Discord. Getting weirdly upset/annoyed or mad at anyone asking about updates. I wouldn't be fully surprised if it's them coming on here to bring the drama to the comment section.
I think he has plans for what he wants to do with his game, but probably lack of funding as well as his personal life getting in the way is probably making this series/game never fully see the light. No hate to the guy though, what he made clearly made a lasting impression to the point where even I come back after YEARS just to check on his game since I barely ever see updates (and I don't like asking in their Discord). If you can do that, then you're doing something right. Even if he does stop support for this game and any other future game he wants to make as well, then that's fine. Sucks to possibly never see anything new from him, but it's fine.
