## What it is
melonJS is an open-source, MIT-licensed 2D/2.5D HTML5 game engine for indie developers, built with ES6 classes and TypeScript support. It provides GPU-accelerated tilemap rendering, physics, audio, input, cameras, and UI in a tree-shakeable ~150 KB module that runs on WebGPU, WebGL 2, or Canvas2D with automatic fallback.

## Use cases
- build a 2D browser game with tilemaps
- make an HTML5 game that runs on desktop and mobile browsers
- create a game using Tiled map editor levels
- write a lightweight web game without heavy toolchains
- add 3D glTF scenes to a mostly-2D web game
- prototype a game quickly in JavaScript or TypeScript
- package an HTML5 game for Electron or Cordova

## When to choose
- you want a complete, batteries-included 2D game engine for the web
- you need WebGPU/WebGL/Canvas fallback with one codebase
- you author levels in Tiled or scenes in Blender/glTF
- you value a small, dependency-free, tree-shakeable bundle
- you prefer a Canvas2D-style rendering API

## When to avoid
- you need a full 3D engine like Three.js or Unity
- you are building native (non-web) games
- you need a large ecosystem of third-party plugins and asset stores
- you require console or native mobile platform targets beyond web wrappers
