I was experimenting with cocos2d-js which runs on HTML5 as well. I made a simple game (incredibly simple) and I have shared the source code. http://woohoogames.wordpress.com/2013/06/28/cocos2d-js-simple-demo-with-source-code/. Or the github repo is here: https://github.com/bluestunt/Cocos2d-js-Simple-Demo.
Simple Demo Game with source code
Thank you for sharing this game. Good work!
