Love this game! I have enjoyed the other Nimblebit titles such as Tiny Tower and Pocket Planes, both of which I still play, especially Tiny Tower. I think it would make a great incentive to players that once they complete all cities, they can select the option of restarting at City 1 again, or playing in Sandbox mode in any of the game's cities that they would like. The progression and building in this Sandbox mode could be done faster than normal, with cheaper buildings than normal as well.

I installed this game on a different device and enjoyed the game. The art style of the buildings and vehicles are adorable. Took me a minute to find this game again due to other games with the same name. I wanted to leave a review because I love this game and how satisfying it is to watch your little city come together. It would be cool to revisit earlier towns without prestiging and restarting but it's not enough to ruin the game or rating.

I'm rating 5 stars because I genuinely love this game, even though I'm so mad at it right now. it claims when you prestige you keep your bux, I had somewhere around 1200 and I lost all but 179 of them. so keep that in mind, don't prestige as a hack just do it when you've completed the game, I guess. still gonna keep playing though.
