The game is kinda ok, but as you progress through the game you need to spend money. The game has an interesting theme, but it's paid to win. The game is also addictive, but the construction time takes longer and longer, it also gets a bit boring. You do the same thing every day, I have played myself but it gets dull, no offence to the creators.
The game has an interesting genre but it's paid to win and can only attract a particular audience, and I'm not part of it. I did quit after a few months of playing, the time goes longer and longer. So I'll rate the game two stars.
