Evaluation
Humanity Must Perish is a short, free-to-play comedic visual novel that launched on September 25, 2017. The store description explicitly describes it as a "short" visual novel with only one meaningful choice, presenting it as a self-contained, complete experience by design. The developer's post history consists of a single major content drop (almost certainly the initial release), one feature patch, and four bug fix posts — a maintenance-only pattern with no indication of planned expansions, sequels, or additional content. There are no unreleased DLC entries, no roadmaps, and no developer statements announcing future content. The game was designed and shipped as a finished product.
Evidence
Store description explicitly describes the game as a 'short' visual novel with only one choice determining the ending — clearly positioned as a small, complete, self-contained experience.
Short description reaffirms the game is a compact visual novel — no mention of ongoing updates, seasons, or additional content.

About this game
Humanity Must Perish is a short, comedic visual novel. It has only one choice, which determines the ending.
As an android whose sole purpose is to save planet Earth from destruction at the hands of mankind, Kyuu minces no words as she announces her plans to extinguish the human race.
For the sake of preserving planet Earth, humanity must perish. Failing that, mankind must be enslaved. Those are the only two options, and if Kyuu has her way, the former will soon become a reality.
Before she can do so, however, her creator makes a proposition: Kyuu will spend one day among regular, everyday human beings, judging for herself whether they are capable of meaningful change or not.
Kyuu accepts this proposition, and thus sets out into the world for the first time, coming face to face with a variety of odd individuals as she decides the fate of mankind.
Will Kyuu's colorful encounters show her the good in human society? Or will the bizarre antics of those who she meets reaffirm her belief that mankind must be destroyed?
Whatever her decision may be, the impressions Kyuu leaves on those she meets won't soon be forgotten. She is a harsh critic, and for a race as flawed as mankind, her observations and misunderstandings will be boundless.
