Hi! Unfortunately, the game is indeed cancelled.
I like yanderes too, so I recognise someone of a similar mind. 🤭
I wanted to link you to my entire audio playlist, but YouTube is being weird for some reason, and keeps linking to the wrong place.
So all I can offer is the playlists it's accepting links for. ^^;
There are a few duplicates, different people do different takes on the work, but if you want a whole series by the same person, I'd recommend JupiterVA:

There's also NaughtPlusZero, who has done the Yandere Dating Sim series and the Christmas special, plus there's a final episode coming up after the special, which is pending but should hopefully be uploaded soon. ^-^

Another who did the Yandere Dating Sim is Daichi Audios, and he did it all in one video, so if you want about half an hour of yandere, he's your guy. ^w^

Or you could go with Fox Hound, there are many choices. 🤭

And if you really want to go dark, there's AudioByTabs with Yandere Fairytale, which is by far the most sinister of the audio series. ^^;

Tabs has also done a genderbent DDLC script of mine, if DDLC is your bag but the lack of a gender-neutral protagonist deters you. 😋
So yeah, hopefully there's something in there that takes your fancy. ^-^
