Sorry but cant see spending over 100 bucks to advance in the game. The more I would spend the harder you make it to win. Finally woke up and pulled the "sucker" out of my mouth....don't get the value of what you charge for a few measly power ups. One step up in power shouldn't cost 50 bucks you guys play on the hope that people get addicted to it....I can get more for my money in Vegas. So sad
