Open Source Touhou Clone

Taisei Project is an open-source, fan-made clone of the *Touhou Project* (東方Project) bullet-hell (danmaku) shooting games. The original Touhou, created mostly by a single Japanese developer known as ZUN, is famous for its intricate, visually dense patterns of bullets, its music, and its vast cast of characters. Taisei recreates the core gameplay using modern open-source libraries (C, SDL2, OpenGL), runs on multiple platforms (Windows, Linux, macOS, etc.), and is free to play. It is not affiliated with ZUN or the official Touhou franchise. For fans, Taisei offers a way to experience classic Touhou-style gameplay without needing Windows or a Japanese gaming environment, and its source code serves as a learning resource for game developers interested in the genre.
