MelonJS

melonJS is the result of our enthusiasm and past experiments with Javascript, and came from the feeling that no simple, free and standalone library was available to develop games. And although still a work in progress, melonJS already allows to easily create some nice games (see the Gallery page) melonJS integrates the popular Tiled map format, allowing to easily design levels using the Tiled map editor, and to focus on the game features itself.
