Yes you can upload any swf file to your site and insert path to it into embed code.
I did not make inserting path to embed code automatic, because probably you'll have a custom params or other code.
I've updated plugin screenshots.
UserCredits will work as before, it means credits will be taken for daily game playing of any game.
I've removed Mochi Leaderboard widget as it will be useless. Also unfortunately there is no bridge to Newsfeed that had shown score results. Because it used Mochimedia API.
If you have any game provider for websites that have any API that has some tools which allow get info from games. I'll appreciate it and consider to integrate into my plugin.
I've found a latest list of popular game websites and hope you will find something interesting.
And yes, I'm not able to define if user plays or just went for a walk :)
If you have any ideas that can be done with UserCredits I can consider them.
Here is an example of using swf file on your site
<embed src="http://ex.com/example.swf" menu="false" quality="high" width="750" height="500" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"></embed>
You just put the location of swf on the site (in plugin it is located in ow_userfiles) to the "src" attribute.
Of course game need to support work on other sites. There are games that does not work if you just copy swf file.
