Space Wars (HTML)

I made this game inspired from the space invaders. Apart from game-play this game has a speciality in the way its built/programmed. I made this game using only HTML, CSS & JavaScript code, all embeded in a single HTML file. 

For the programmers out there, you may be interested to know that I made the game art only by using 'div' elements with CSS. It was an amazing experiment. Its obviously time consuming, but fun to see the results. 

Your may also try to make one, a simple but interesting game
