I downloaded the android version and after a shaky start understanding the game mechanics, I now love it. There are a couple of errors, one is that if you don't rank first, you need to exit the app to play again. Also, sometimes once AI players are killed off you are still matched against them but they are called GHOST. Although I haven't lost a ghost match (maybe you can't?) I would feel cheated if I lost to a defeated player.
Anyway, great game. I am now going to download all your other games. Keep up the good work :)
