I am playing Tiny Tower for a month and it gets boring each day passes by until they released an update which let the player earn cash (Most useful form of money in the game). You can use this cash to upgrade your elevator to make it go up faster. Restock instantly and even trade it to earn coins (Use to add floors to your building).
They enhanced some of the features. Add more challenges to make it more exciting. They put stars to a floor corresponds to a bitizen’s dream job.
Everything runs smoothly, and for me they did a great job.
