I like this game but one thing is bad why you dont fix problem? When buy a weapon and upgrade at level 3 and play mission but when I come back after exit game I dont saw weapon upgrade in my bought list even i lost all my coins and don't get back. Fix it problem i have 3 or 4 time game uninstall and again install and again then same problem then start, I have irretate this issue kindly fix it otherwise you remove the game... this is irretate issue of game comunity. Now thats why one star review
