I gave this thing a look, mainly because this is the first time I've seen a game marked as "Complete" with a version as low as "0.31" of all things, and I got curious about what's going on here...
Reading through this only made more confused tbh.
On the one hand, the thing has endings, so I guess you CAN argue that it's complete.
On the other hand, the thing seems unfinished or bare bones in a lot of ways, to the point where it kind of feels like a weird demo...
Oh, and the English is terrible. Yes. I did see in the thread that English isn't the dev's 1st language and whatnot... but how far that excuse goes depends on what their native language is and how long they've been practicing English. (If it's more than 10 years at the time of making this thing, then this atrocious writing has no excuse tbh...) If they haven't been properly practicing and using English, I have no idea why they'd bother attempting to make a VN of all things in English...
Leaving that aside, I don't know if this is the dev's 1st project or not, but it certainly looks that way. The story is disjointed and flows weirdly. The H-scenes are too short and bare bones. The characters aren't all that well developed...
Dunno how they went from this, but I definitely recommend a lot more reading before any more writing. There's potential in the idea(s) here, but they needed more work than what was put in.
Still, not the worst thing to waste some time with, just a tad disappointing that more work wasn't put into things.
