At first I used to love this game but at some beginning levels it force you to spend the cash and the material for buildings are really hard to collect and at the factories the things take too much time to get ready which is really ridiculous and the piggy bank I hate it all of your money goes in it untill it become full and you have to pay fee to open it which I really don't like plus it beacomes boring at the levels upto 25 but Atlast I am really disappointed.
