Simple HTML Game integration

I need some changes to an existing website. I need someone who can make small modifications to the open source HTML5 Game "Browser Quest"

Online demo: [url removed, login to view]

The idea is to add a few social functions to the game and to integrate them with our social network (Joomla + Easysocial).

My website: [url removed, login to view] (protected URL)

Modifications:

##################

1: Game must save state on server for each user. When a user closes the game and starts playing on a different device then game will resume where the player stopped. The game should create 1 character with "joomla" username for every user / player.

2: players must be able to invite their friends from my website to play the game
