This whole thing was written in HTML5, CSS3 and Javascript (using small bits of jquery). For the basics I was following the "Exploring HTML5 Canvas" Tutorials (Part 1 - 6) by Devtouch. Thanks for the great Tutorial!

For some other stuff, like how to write objectorientated javascript I was following the tutorials over at http://www.codecademy.com/, which is a really great site to learn Javascript and also other languages.

If you understand German you can also read my blogpost about this site: "Pacman in HTML5 Canvas".
