Awesome! Now just add first-person view, and a 3D map, and different weapon loadouts, and classes, and... I may be getting carried away.
Haha yeah, there's a lot I could do: Capture the Flag mode, player skins, Twitter/FB authentication to keep scores across games, various weapons, more powerups, ... I'll see how it goes :)
This is a tech demo of open web standards. Persona! :P
