FWIW- I did a ton of research on friend to friend sharing in a previous gig. I found time and again that site based currency (like your points) was the most attractive motivator to encourage users to refer friends to a site. If you do incent users, you'll want to make sure you have suitable fraud tracking system since users will go out of their way to figure out how to game the system. Your site design is really clean versus other flash game sites I have come across in the past. Nice work!
