I had to change my review... After spending over $20 on upgrades. My game started to glitch. I then thinking of a quick fix uninstalled and then reinstalled the game. To my amazement the problem was not only not fixed but now all of my data and progress had been erased. I contacted the developers via google review as well as Facebook and still have not received a reply. So that's why my rating dropped down to a one star. I will update this rating as soon as the problem has been fixed.
