The game has potential, but after spending a week actually going backwards with progress due to a very poor matchmaking system and being put up against much stronger players and constantly losing matches (your progress goes down 10 points every time you lose a match), I've decided to change my review. I'm sure the developers thought process was this would encourage new players to spend money to be more competitive, but in my case, I'm just going to delete the app and not bother with it anymore.
