Saddly no one had the interest to pick it up. I feel it has potential
That's mainly because the game, while written in twine, isn't set up like a normal twine game. I'm no expert on coding languages, but it looks like it uses twine as the base for passages, but straight up uses Javascript or something to handle all of the events/variables/etc. It might not be JS, but it's definitely not Sugarcube or whatever twine uses natively.
That alone makes it hard for someone to pick up and run with since they have to know how the game is coded, and then know how the dev actually works it into the story.
In all honesty, if someone really wanted to make a version available for people to mess around with, it might just be better to convert the whole game to sugarcube, since from my experience messing around with it nothing in it is really super dependent on JS and can be done just fine in Sugarcube. I mean, I've mainly just poked and prodded at it, but still.
I'm not skilled enough to do all that, nor do I really want to since I don't have the time. I'm sure there's people that are more skilled than I am and could use what's already there, or convert it into an easier to edit format, but in all likelihood that's not going to happen any time soon.
