Box2dweb is really easy to use and once you have mastered it you can create almost any html5 game beyond your imagination.
Where to download the Box2dweb framework
Box2dweb is hosted on GitHub https://github.com/hecht-software/box2dweb, there are lots of files on the above page but all you need is either Box2D.js or it’s minimum version Box2d.min.js which you will then include in your index.html game page.
The guy is a pro and he knows his business really well.
Go ahead and download the framework and start working on it then show me your game in the comment box below!
