I have played this game on and off for over two years and it was fun. If your not going to pay money you can definitely move up but it's a long grind. However recently I can't even play the game as it crashes every time I try to open it. I unslinstalled and then re-installed, went through the tutorial and linked my account again and now the game just crashes every time again. Glad I didn't actually spend any money on my account.
