Buggy. I am convinced that the program has a memory leak on Android. I have it set to store info on my SD card. Additionally, it routinely bugs at the "Finding Opponent" spinning dial, starting the match while I am still at the dial screen. Additionally, it routinely drops carrier during gameplay. As such, I cannot compete in the game. I can neither gain, nor maintain rank. It is for these reasons that I cannot justify investing dollars into this game, and I advise the same to others.
