Space Dinosaurs was my entry for a HTML5 game development contest ran by Microsoft in 2011. It's also my first serious attempt at a game on that platform. Because it was written in 6 weeks time, and I'm not much of an artist, it's not all that great looking. But it was quite a fun project and has led me to consider HTML5 as a promising gaming platform.
Space Dinosaurs is open source, if you're interested in creating web games it may have some interesting concepts in there for you. But it's not something I'll be updating as my hobby project is now BladeGame.
