Little City is a browser game project building a tiny, explorable planet version of real cities, starting with Taipei. Little Taipei renders the city as a small, cel-shaded globe with hand-placed landmarks like night markets, temples, Taipei 101, and the river, positioned using their real world bearing and distance from each other so the layout feels recognizably like the actual city. The project's stated goal is to eventually build a similar small planet for every city in the world, with Taipei as the first one. Running it locally just means cloning the repository and serving the folder over a simple HTTP server, since the game is built with native JavaScript modules that need to be loaded from a real web address rather than opened as a file directly. Once running, a player moves around with the WASD keys, jumps with the space bar, and interacts with objects using the E key. The project deploys through a service called Antics for its multiplayer features, like shared rooms, synced players, emotes, and leaderboards, without needing to run a separate server. Running it locally gives you solo mode only. The project is explicitly built to be easy to contribute to with the help of an AI coding assistant. The city is made of small, self-contained building and landmark files, so adding a new landmark or fixing a road is a naturally scoped task. Contributors are encouraged to open the repository in Claude Code or Codex, point the assistant at the project's contributing guide, and ask it to add a specific landmark, place it correctly in the city data file, and confirm it renders without errors before opening a pull request. One landmark per pull request is the suggested scope. The project is built with the three.js graphics library and is released under the license included in the repository.
