Thanks :) BTW, We tried it on hipchat and worked perfectly.
Glad you liked it. It can get pretty crazy with more users. The art and voice overs were all done by the team except for one of the player sprites and a logo (which was taken from a freely available art pack). You can also use a phone that supports swipe gestures as a controller. Having one screen with multiple people on the phone was something we felt was pretty nice :-)
