-[melonJS](https://melonjs.org/) is an open-source HTML5 game engine that empowers developers to create 2D games using modern JavaScript and TypeScript. Built with ES6 classes and bundled using [esbuild](https://esbuild.github.io), it provides tree-shaking support for optimal bundle sizes.
+[melonJS](https://melonjs.org/) is an open-source 2D game engine designed for indie developers — post-processing effects, custom shaders, 3D mesh support, polygon-accurate physics, modern Tiled workflows, and high performance, all packed into just over 100 KB minzipped of vanilla JS/TS with no toolchain lock-in. Built with ES6 classes and bundled with [esbuild](https://esbuild.github.io).
