My online multiplayer demo via HTML5

http://www.reddit.com/r/modit/comments/19nz44/submissionrubble_rumble_a_multiplayer_class_based/

This is the engine that I'm going to be building my game on, but atm I don't know if it can handle enough people for me to advance further and add content. This is a game written in HTML5 with that is connected to a node.js server. The GUI is more or less what we're going to end up going with [Although make things like the victory and scoreboard screen more visually pleasing]

Any feedback, thoughts or noticable bugs?
