I just started playing this and its very good so far this is amazing for an iOS game once I complete this Ill be moving to the sequel which looks just as good well great job to the developers. The only thing u guys can make the movement controls a little easier but its not that big of a deal.
Edited
So I was thinking this game should have a multiplayer I could see it now matchmaking online it could work. Consider it.
