I am summing up all the reviews in my own. 1. The game is glitchy and every time it says I have 4 customers left it glitches and ends where Im at. The bar that says how long till the customer leaves stops short and they leave before it runs out 2. Too many ads right after a level itll give you an ad that will sometimes go black then you have to exit and go back in the game. 3. The amount of gems you need in order to upgrade is crazy. It causes you to buy and I don't have that money.
