Obviously there's all sorts of simplifications in this, but ultimately what people are expressing I'd speculate boils down to the core idea about how a story is typically constructed:
You build up, up, up, up, reach the climax of the plot, and then have an end to the story.
But Instinct Unleashed feels more like
You got all the usual points. We got the initial setup, we slowly ramp up what's going on, we got incidents along the way that increase the tension leading up to the crisis; we then go to the climax (and not in the porn game sense) but ... the climax is the resolution, and then we are chopped right to the end. There's basically the entire 3rd act missing: chapter 1-13 are Act 1 and 2. Chapter 14 is the entirety of the 3rd act. It's wildly unbalanced.
This can applied to the subplots of various of the characters too, in my opinion. With a lot of them you get somewhere into "act 2" ... but then it's more or less just over.
Obviously, this is just one archetype of storytelling. There's many other ways, and not everyone will agree on how exactly this should look. But I'd certainly find it notable how many are of the same opinion, however precisely they come to it, that the "ending is rushed"; and for me this discrepancy here is the most likely culprit.
And yeah, obviously, you will also get some complaints about either the level of choices (which you really don't have) for the ending, the obscurity of how to get the endings, or just simply any one of not-enough-porn/harem-whatever.
And further yeah, you can complain again that this is kinda surface-level and not actually making very specific story suggestions, in the sense of "this is the exact sequence of events that should have happened". But writing is not paint-by-numbers (even if there's a paint-by-numbers graph up there). It's maybe 5% what you do, and 95% how you do it. So it's really just impossible to say in a vacuum; though probably it boils down to "mayor-was-the-bad-guy-all-along" being both the denouement and resolution in the exact same scene, and the whole futa-serum-whatever-research-center-real-estate-plus-murder-mystery-plus-abducted-futas-or-whatever plot just being ... I don't know, casually shoved to the side I suppose (but then also some of the character arcs, so it's not just a simple linear narrative problem anyway).
