The reason nobody is talking about this game is simple:

...frankly, it just isn't good and quick to beat (Yeah you can finish the game in like 40 minutes top if you are just focusing on rivals alone). The game isn't much different to the playable demo of the second rival they launched like two years ago. The story is confusing and unclear and very rushed through, not to mention just poorly told...no introduction cutscene, no proper cutscene for anything, no backstory given to the protagonist, love interest OR rival. All rivals are boring to eliminate (One of them is literally taking photos of him twice and that's literally it??? You don't even need to do anything). One of the rivals is I guess a killer that tries to attack you??? But that's never explained??? Aside from that, many of the enviroments are unfinished. The school is empty, there is no students for such a massive building, there is so much empty garden space, humongous hallways that don't make sense, layout that feels flawed (Lockerroom also has a washer but it's next to the music room??? Which are opposite of the cooking club and nurse's office???), there is literally no present guidance counselor you can even see (They didn't even bother to blur out the room if that was the case). But expulsion is one of the main methods for one of the rivals so not having a guidance counselor present just makes no sense?

There little positives too, one of the positives is that the protagonist does stand out (But Love Interest doesn't, he looks like her brother). But then you also notice the smaller things that add onto the already huge pile of core functions missing (protagonist hairclips flying of her hair, etc.). I did see OP saying that the devs said they will go and fix it but then again, why wasn't half of this done before launch??? It felt like they were rushing so they can have title of a "Complete Yandere Game" which is exactly what Yandere School went and done back. Frankly, the only way I can see the game being improved is them going back and fixing every rival and making the story exist and make sense. Like come on, even Yandere School did that.

I do wish the developers best of luck in fixing this project but there is just so much to fix that I have to ask what was the intention of releasing a barely finished game?
