Fun at first, then food starts taking way too long. Hours and hours of waiting. It takes the fun out of it. Most decoration costs way too much also. Take out orders are also usually dishes that take hours to make..
Also, i lost all my diamonds because i accidentally clicked on them to buy stuff or skip assignments. It happened a few times already, i was just scrolling and clicking on something and then i misclicked and all of a sudden i bought extra stuff with my diamonds even though i didnt mean to. Why doesnt the game ask you if you are sure you want to spend them? If that will be resolved it would get more stars. I never have bought nice things with diamonds, only spent them on stupid stuff i didnt want.
