Don't bother installing this greedy money grab! The paid items are so freaking expensive AND even with the paid items, the game is rigged to be nearly impossible. 1 energy takes 5 minutes to recharge and you need 5 per round. Computer generated opponents constantly going out in the very first turn. The developers are so disgustingly greedy with such a set up. Even though I have all sounds turned off in the game, the ads are full blast volume and most don't have a mute option.
