I may be mistaking, but as only a few hours had passed between your first 2 message, I have to ask. When you say you published it, you mean you send it on your dev account on the app store for submission, not just export from C2, right ?
If you just exported it from C2, you can export it as many times as you like. It won't publish itself. And even if you sent the same game twice, they wouldn't accept both.
You can export your game with node Webkit too, it will make you an exe file and then you can start selling it once you've got a distributor, or make a store online to sell it.
I didn't get your last sentence. If you wanted to know if you could export it to facebook, yes you can. Just try it, it will build you the necessary files for submitting it onto facebook.
