I've clicked all the mouse buttons, and every button on my keyboard and absolutely nothing happens. The tutorial doesn't say what button to tap.

Mine is: 92939

I had another problem. After updating the game, the fitness club cannot be restored constantly. We have to wait 4 hours for this building to work again. This has never happened before, it really ruins the game. Has anyone been able to solve this problem?

I installed the game for my two kids. How can I save/load two different cities ?

The game description says "Let's start working right now, tap-tap the DOWNLOAD button!" Where is the download button? Is this supposed to be free to play?
