イツカノヨル (unityroom free original, Unity1Week 2023, no official English title): its lineage, descendants, and standing in Japan
01What this origin is
The free original this grew from: イツカノヨル, released free on the Japanese game jam site unityroom in October 2023 for the Unity1Week jam's "one button" theme, by creator Indigo Ingots (script, planning, and programming) working with artist polaritia and composer Kazura's MUSIC. Per its own game page, it already carries the same premise and structure this lineage grows from: a five-minute, click-only story branching across your choice of whether and when to press the execution button in front of you. 5omeday on Steam is not a new work borrowing that DNA from outside; it is a commercial edition of this same free jam game, adding full voice acting, extra endings, and English and Chinese language support on top of it.

5omeday Buried gem
Per Steam's own listing, if she moves strangely or seems about to hurt you, you press the button in front of you right away, and the execution happens immediately. A single playthrough runs about five minutes, played with nothing but clicks, and whether you press the button, when you press it, and which dialogue choices you make branch the story across 13 different endings shaped by your curiosity and guilt. It began life free on the Japanese game jam site unityroom in October 2023, made for the Unity1Week jam's "one button" theme by creator Indigo Ingots (script, planning, and programming) working with artist polaritia and composer Kazura's MUSIC. Steam's own developer credit lists Indigo Ingots and Starlit Chronicles Studio; whether the latter is a separate team or Indigo Ingots' own commercial-release name could not be independently confirmed, so this is stated as-is rather than guessed at. This commercial edition adds full voice acting for the dragon girl Mira (voiced by Nako Natsuki), additional endings with new music, stills, and character art, Steam Achievements, a gallery mode, and English and Chinese (Simplified and Traditional) language support on top of the free original. Published by Waku Waku Games, a small Tokyo-based indie publisher, it released January 28, 2026 and sits at Very Positive, 89 percent over 307 reviews (274 positive, 33 negative per Steam's own review API). A paid title, not free, fully launched and not in Early Access, with no AI-generated assets; per Steam's own content descriptors it carries only a General Mature Content tag, with Steam's own notes stating outright that it 'does not contain bleeding, violence or sexual content.' It supports Japanese (full audio), English, and Simplified and Traditional Chinese, and while about 90 of its 307 reviews, some 29.3 percent, are already in English, and it did draw two pieces of Western press — AUTOMATON WEST reporting it had sold over 10,000 copies, and Niche Gamer covering backlash over its execution-button premise — neither is a review: Kotaku's page for it turns out to be an auto-generated database listing with no byline, and Metacritic lists critic reviews as not yet available, so this stays a game the West has talked about without yet actually reviewing.
