The game has achievements but sadly, not XBL ones. So if chasing down achievements in general keeps you interested in a game, A8 offers that!
We do have more things planned for Windows Phone and Windows 8. Here is the blog post I did after we announced our latest partnership with Microsoft:
Dynamic Duo: Gameloft and Microsoft Team Up!
It talks about a few titles that are already out and a couple that haven't come yet but are due out before the end of the year. I know we've got a lot of cool things coming up next year as well, so definitely be sure to keep an eye out for other GL titles
