关于此游戏

"生活的乱麻苍白无色，唯谋杀的猩红之线贯穿其间。" —— 柯南·道尔
《朱线》——墨的世界里，只有一缕红。
煤气灯年代，虚构的北方海岸，桑克利夫庄园。三十年前，一位上校从战火里带回一件他本不该碰的东西——圣物「赤缕」，一束红得不像人间之物的编结丝线。三十年来，它锁在匣中，绳缠火漆，无人得见。今夜，继承人的成年礼上，这只匣子终于要开了。
老派的公平推理。
以维多利亚感官小说的笔法讲述：一位叙述者接着一位叙述者，一份文书接着一份文书。读老管家诚实的日志，比对全宅上下的证词，把疑点钉上线板、用红线把它们收紧——「线索」二字，本就从线上来。
属于那个世纪的谜题。
没有硬贴上去的小游戏。每道谜都是维多利亚客厅里真实存在过的玩物，也都有它非在故事里不可的理由：晚宴上的韵文字谜、席次的尊卑安排、守着亡者圣物匣的解环锁、以及那缕线本身的缠与解。

AI 生成内容披露

开发者对其游戏如何使用 AI 生成内容的描述如下：

Some of this game's content was made with the help of generative AI tools:

Music — all musical cues were generated with Suno, then edited by hand (trimming, level-matching, loop points, dynamics).

Art — a number of background plates and figure elements began as AI-generated images. Every one was then worked by hand — desaturation, tonal grading, cut-out, retouching and compositing — before being rendered through the game's 1-bit dithering pipeline.

Localisation — the game ships in ten languages. Eight of them (Traditional Chinese, Japanese, Korean, German, Spanish, French, Brazilian Portuguese and Russian) were translated with the help of an AI language model and then checked in-engine.

No AI generation happens at runtime.

Named characters' faces are never AI-generated — their speaking portraits are baked from public-domain paintings.

成人内容描述

开发者对内容描述如下：

The Scarlet Thread is a Victorian-style murder mystery. It contains non-graphic depictions of death (bodies rendered in 1-bit ink, with no blood or gore shown), descriptions of wartime violence, an off-screen killing, insinuated alcohol consumption, and a plot involving the covert administration of laudanum, a period medicine. No nudity, no sexual content, no profanity.
