A little JavaScript sample of code

I did a little version of the "Space Invaders" game on JavaScript to go into JavaScript for HTML 5, and have some code to show, all the code that I develop now is for my company...
The game is a Chrome Extension app, you can download the source code and the CRX file from:

• SRC: http://tras2-desarrollos.es/space_invaders_src.zip
• CRX: http://tras2-desarrollos.es/space_invaders.crx

To execute the game only download the CRX using Chrome and install it.
