Panda.js HTML5 Game Engine
Another fantastic HTML5 Game Engine I’ve found is Panda.js. It like many others hosts a bunch of features to help you quickly and easily develop games. This is because native to Panda.js is mobile support along with a robust particle engine, physics engine, and sound manager. It also has a dynamic loader, bitmap font, and plugin support.
Google Analytics also ties in well with your app allowing you to track the in-game events that occur in your application. CocoonJS is also included allows you to natively wrap your app too. Panda.js brings a lot to the table, and you can get it here.
