# Flow NGIN
A simple cross-plattform instancing-oriented game engine with focus on full WASM-compatibility.
You may want to use this engine if:
- You heavily rely on instancing (many instances of the same model)
- You need full browser compatibility
- You like to use Rust exclusively for all platforms
- You don't need a GUI for game development
- You prefer code over low-code
