Multiplayer Pacman with node.js and socket.io (multiple rooms)
Trying it is as easy as download and write "node app.js" in a console (assuming you have node installed). If you dont download the node_modules package you must install them: "npm install express" & "npm install socket.io".

Next step should be improve performance in mobile phones, and allow them to have a way to move their pacmans...
