first of all no matter how good you are and how much you play, always you will feel that you need life long to progress unless you dont care about your money. i understand that sometimes its ok to spend money to have fun but not that much of money. and the worst thing is that the price of everything is becoming higher as you progress. another issue that the game sometimes crash and sometime you lose products you have purchased as pattern/decal and coins. and if you contact the support center they feel like a robot the talk to you very nice no matter how angry you are (politics to let you feel special). in the end be careful and dont spend much money because you will get addicted and you will feel sorry about your money so it will be hard to quit the game
