NIGHTFALL — The Last Archive Line

"There is no missing-person report in this file. The property was lost, not Mara."

The night service is the last archive line: a train that runs between stored places and the records of the people who lived in them. Butch is its lost-property clerk. Claim 1978-0412 left a case on board, and he cannot leave an unclaimed case alone.

Every chapter is a different world, and plays like one

• Night Service. A carriage told in windows. Drag, swap and zoom painted panels until the right edges meet.
• Borrowed Light. A city that runs on light borrowed from the train. Run its rooftops in the rain, on the bell.
• Echo City. A sunlit 3D city with two tickets numbered 43. Talk, look closer, and work out who M. Venn really is.
• The Painted Country. Rosa's childhood drawings, painted over by the archive. Your mouse is the brush.
• The Museum of One Answer. The archive has already filed your journey. It wants one clean answer about Mara.
• All Worlds at Once. The Conductor keeps the line running. Face him across every world you have crossed.

Five magic stones are hidden along the line. Find them all and the last carriage opens.

About 3.5–4.5 hours. Two endings. Saves are automatic. English and 简体中文 (Settings → 中文).

一列夜班列车在被封存的地方之间穿行。你是失物招领员布奇，要把一只无人认领的箱子送回去。六章旅程，每章一个世界、一种玩法：拼板解谜、雨夜屋顶、3D 城市调查、被涂抹的乡野、唯一答案博物馆，以及与列车长的终局对决。约 3.5–4.5 小时，两种结局。在设置里选「中文」即可切换中文界面和字幕（配音为英文）。

安装：Windows 解压后运行 NIGHTFALL.exe；Mac 解压后拖进「应用程序」，第一次右键点 App →「打开」（macOS 15 可能需要到「系统设置 → 隐私与安全性」点「仍要打开」）；Linux 给 AppImage 加执行权限后运行。

AI disclosure. Generative AI was used throughout development, under the team's direction and with the team's editing: the paintings (title, Chapter 1, cutscenes), world panoramas and some textures (OpenAI image generation); some 3D source meshes in Echo City and the Museum (Tencent Hunyuan 3D); the English character voices (ElevenLabs); parts of the writing and the Chinese translation, and much of the code (AI assistants including Claude, Codex, Qwen, Kimi and Gemini).
