The game is amazingly nostalgic however the coin system to join games is faulty. Watching ads to replenish them has me usually sitting through ads WITHOUT rewarding the promised coins. I can't find anything that you can earn other than a rank title. The rank title is secretly hidden behind a money hook as well by simply kicking you from games mid attack phase and robbing you of the coins the game cost to play in the first place. I'm disappointed to say the least and won't spend money on this.
