The game play is good with a nice pace of progression through the game provided that you pay not to have ads. The problem is that the game freezes, meaning that I have to force close it and reload the game constantly, making it pretty much unplayable at this point. UPDATE: I emailed as requested and nothing happened. Shouldn't need to email them anyway. Stop expecting people to pay if your not going to debug the game.

Unplayable unless you spend money to allow the game to play when turned off. Otherwise you need to leave the game running for hours on end to gain enough money to build more buildings. I did this and still cant move forward in the game. Nothing to show what you need to do next. Stuck now. Also not going to spend any money on a game in the first few weeks of starting playing it. Going to un install the game now.

WARNING since update causes phone to freeze and lock. Do not install this game RUBBISH started ok, Then a few days ago I paid for the ad free version. Now theres been an update and suddenly the game doesn't open or it freezes within 20 seconds of opening then closes. Either fix it or give me my money back. Don't see why I should pay for something if it's not working Reply from game developers - if you reinstall the game then it doesn't save your progress so loose everything 😠
