tf bug error I logged into the game today, but everything was exactly the same as yesterday. None of the buildings I built today were saved, and all my progress is gone. Is this some kind of time/server error? Honestly, all the time I spent playing this game feels completely wasted. Extremely disappointing. 0/10.

Awasome graphics and best user interface,easy to earn money from commercial buildings, And lots of public properties and facilities Available to build for people, there are some missing items such as bridges, Railway network, Airport, Ships yards, bus stop and mining etc but overall this game is better than dozens of City island games

It is relaxing, I love the graphics but it is challenging. Also, if you do not have the money to get gold like you want to, at least you can look at ADS to get more gold, I love all the houses in the different places. You can buy
