1) We have already introduced 'Big Foot' and we assure you there are many more to come :)
2) We do plan to introduce walls... just figuring out how much impact it would have in the game play.
We will be adding advanced features like alliances and leaderboards once we have fine tuned the basic game play. Stay tuned.
