A bit tedious

Moving buildings around is tedious and clunky. You can’t spin the board to see different vantage point points. Buildings also turn in only two directions so the aesthetics are a little odd when you’re trying to build roads a certain way. Lastly, they recently inserted random pop-up ad videos. I’ll be deleting this one despite having had it for a while.

New Updates

The new update to the game deleted my previous build. Not only that, but this new update is draining battery at an astronomical rate.

Have not been able to level for a week now. Can make gold unless we watch commercials. It may be to delete and move on.
