Taisei Project is a free and open-source Touhou Project fangame: an original top-down vertical-scrolling bullet hell (danmaku) shoot 'em up set in the Touhou world. It is written in C11 using SDL3 with an OpenGL renderer and runs on Windows, Linux, macOS, and browsers via WebGL.
Use cases
- play a free open-source Touhou-style bullet hell game
- play a danmaku shmup on Linux, Windows, or macOS
- play a shoot 'em up in the browser via WebGL
- find an original Touhou fangame with its own story and music
- study a C11 game codebase using SDL3 and OpenGL
- run a bullet hell game on Nintendo Switch homebrew
When to choose
- you want a polished, free, cross-platform Touhou-style bullet hell shooter
- you want to play a shmup directly in a WebGL-capable browser
- you want an original danmaku game that doesn't require knowledge of Touhou
- you want a real-world C/SDL/OpenGL game codebase to learn from
When to avoid
- you want an exact clone or remake of a specific Touhou installment
- you need a game engine or library rather than a complete game
- you need official console support (Switch build is experimental homebrew)
