About 上下文溢出
上下文溢出 (“context overflow”) is a free card roguelike demo for the browser with an AI joke at its centre. You play a newly minted large language model taking odd jobs from all over the world and passing hard tests, while uncovering a secret hidden behind them. Instead of attacks and health bars, your cards complete the workload of each request, and every card you play fills a shared context capacity that must not overflow: the page's tagline reads “每打一张牌，都离上下文溢出更近” (every card you play brings you closer to a context overflow), and the goal is to complete, modify or cancel every request before it does. The developer, wheelg, announced the demo on V2EX in August 2026, writing that it was vibe-coded with Codex on about three weeks of usage quota, that vibe coding can easily let a project spiral out of control, and that AI still struggles with a game's style and story text, which needed polishing by hand. The developer added that the demo is not hard. The language model in the story is fiction; the game calls no AI model. In Simplified Chinese.
How it was built
Partially verifiedIn a V2EX post (11 Aug 2026) the developer writes: “最近尝试 Vibe Coding 了一款卡牌肉鸽游戏《上下文溢出》，Codex 是真给力啊，花了 3 周左右的额度肝出了一个像模像样的作品” (I recently tried vibe-coding a card roguelike, Context Overflow; Codex is really strong, and about three weeks of quota produced a respectable piece of work). The developer warns that vibe coding can turn a whole project into a mess if you are not careful, more so in games, and that AI's handling of a game's style and story text is still unsatisfying and needs polishing by hand. The post does not give a share of AI-written code or name a model.
Vibe-coded with Codex over about three weeks of usage quota, per the developer, with the story text polished by hand. The live page is a React app whose script also bundles three.js and react-intl (observed).

“最近尝试 Vibe Coding 了一款卡牌肉鸽游戏《上下文溢出》，Codex 是真给力啊，花了 3 周左右的额度肝出了一个像模像样的作品”Verification notes: AI use, the premise and the developer's caveats come from the developer's V2EX post (11 Aug 2026, 16:22 UTC+8) and a reply in the thread, re-read on 6 Nov 2026; the post links the demo. The post says the game was vibe-coded with Codex but gives no share of AI-written code, so the evidence is medium. The tagline and goal text come from the page's metadata (html lang zh-CN). The game's 1.45 MB script, fetched on 6 Nov 2026, makes no network calls besides loading its own files and analytics; no AI service is called. The LLM premise is the game's fiction. The romanised title is ours; no official English title was found. The game was not played. No release date is given; the demo was public on 11 Aug 2026. No name, location or team size is given.
