Unless the dev has a miraculous change of heart (unlikely), it is abandoned in game/VN form.
Apparently, it will eventually be released as a series of books. But the current hanging plotline… I wouldn’t expect resolution and time this decade.
Personally, as someone who has seen stories go on hiatus since the 90s and 00s, I don’t see it ever resolving. Every once in a a while it does happen but it’s rare enough to not be worth keeping your hopes up.
