I'm trying to figure out a way to modify an existing Flash AS2 game, so that scores can be shared on Facebook in a simple 'I scored 8/10' way. I don't want to set up a Facebook App or mess around with APIs. I'm trying to think of a way to do it within the existing code, via Open Graph and browser URLs.

For example, if I score 8/10, have the swf redirect to score8.html, from which the 'Share Score' button will prepopulate the Facebook post with 'I scored 8 / 10'. Perhaps it could be done within an iFrame so as not to take the player out of the game browser?

Any thoughts? Thanks in advance.
