The current patch makes the game universal. For me, it said $4.99 on the iPhone App Store, but it told me the update was free since I had already purchased after I clicked purchase. The same thing has happened to me in other games when they go universal.
It looks like there is a buddy list as well as a player lookup so I suppose that is promising.
Thatās as far as Iāve made it in the app thus far.
