This game is awesome, but can’t sign-in with facebook account

I like this game and everything about it. I think you should add more game modes, maps, and at least a team deathmatch. I was also wondering how I can sign in on my facebook on the mac version so that I don’t restart my whole account. That’s one thing that held me back from playing the mac version over the facebook version. Please add facebook support, thank you. other than that, awesome game, Love it.
