This would be a 5 star game bug i give it a 4 star
reason:Am on android and I finished the game and when I downloaded the new update,I dint delete the old one and when I press update,it says it won't install error etc,the only way is to uninstall the old one and when I do and download the new one,all my hard progress is gone
To fix this,I'd say put a cheat menu
