Flappy Swift

A DOM-rendered WASM game in ~100KB, written in Swift.

A technical demonstration of ElementaryDOM and ElementaryCSS rendering performance, implemented as a "Flappy Bird" clone. This project serves as a playground for exploring the capabilities and performance characteristics of DOM-based rendering in Swift.

Intentionally, Flappy Swift does not use Canvas or WebGL, but renders directly to the DOM instead. Every animation frame is going through the full reactivity-based reconciling/V-DOM logic without any special tricks or shortcuts.
