Rights holder / original work: Kingsoft (金山打字通 / Kingsoft Typing)
The README calls the game a web tribute (致敬版) to 生死时速, a classic game in Kingsoft's typing tutor 金山打字通, and it uses that game's title and its police-and-thief typing chase. The developer says the image assets were generated with Codex; no source mentions original Kingsoft assets, or a licence or permission from Kingsoft. (GitHub (CH0918))

About 生死时速 / Speed Chase
A browser typing game in which a police officer chases a thief through an isometric cartoon city. You choose a side and the vehicles for both characters (on foot, bicycle or car), then type the English passage shown at the bottom of the screen: fast, steady typing speeds your character up, while mistakes and pauses slow it down. The officer has to catch the thief before the passage ends; the thief has to finish it first. The README lists several practice passages or your own pasted English text, live speed, accuracy, time and error counts, five result ranks from Bronze to King, personal bests, a shareable result poster and a Chinese or English interface. The developer, CH0918 on V2EX, says it recreates 生死时速, a minigame from the Kingsoft Typing tutor (金山打字通) that the developer played in primary-school computer classes and could only find for Windows, with no online version, and that it was vibe-coded directly with Codex; Codex was also used to generate image assets. After the first, single-player version the developer added two-player online rooms, which we found in the live build. Free at typingchase.com, with the source code on GitHub.
How it was built
VerifiedThe developer's V2EX post says that, finding the original only on Windows and with no online version, the developer vibe-coded a version directly with Codex (直接用 Codex 来 Vibecoding 一个版本出来), at first single-player only. In replies the same day about the game's visuals, the developer said that Codex was mainly used to generate image assets to make the game look richer, adding that GPT can produce assets with transparent backgrounds. No model or code share is given, and the README does not mention AI.
Vibe-coded with Codex as a single-player web game, then extended with two-player online rooms after feedback on V2EX. Per the README it is written in TypeScript with Vite, draws with Canvas 2D, plays sound through the Web Audio API and is served as static assets on Cloudflare Workers; map and character images are preloaded before the first round. The live build lists open rooms through the site's own API and connects the two players peer to peer (WebRTC).

“直接用 Codex 来 Vibecoding 一个版本出来，目前只有一个单机版本”Verification notes: The AI claim and the Codex-made image assets come from the developer's V2EX post (28 Aug 2026, 12:52 China time) and the developer's replies in that thread the same day, which also announce the two-player rooms. The post links typingchase.com and the GitHub repository; gameplay, features, interface languages and the tech stack come from the README, which does not mention AI. We opened typingchase.com (title 生死时速 - 打字游戏, page language zh-CN): its script contains Chinese and English interface text and the room feature (create, join and leave rooms, peer-to-peer connection). Players reported online-room sync problems on 28–29 Aug 2026; whether these were fixed is not stated. In one reply the developer suggests players can have an AI write a custom passage and paste it in; the game itself calls no AI service (none seen in its script). No licence file was found in the repository, so the game is not tagged open source. The repository's commit history could not be read from our environment, so the release date is left open; no source states the team size. The V2EX view count is not recorded.
