Good city builder

This one is pretty good, it's pretty easy to learn and it doesn't pressure you to spend real world money every chance it gets. There is also plenty of opportunity, if you take your time, to increase your rank and open more building options and make gold. Also I enjoy the boost option that the paradise island game doesn't have.
Down sides: there's no storage option for building when your restructuring your city.
The buildings only go two ways, and although this saves time for designers, it would set your game apart and allow more creativity for the customers.
It's a pain to remove trees and shrubs after you buy expansion land.
I can't figure out if some structure need certain things prior to building them, so sometimes I have rando water ways, which looks odd.
Rando pop up ads. I'd pay a dollar to never see one again.
On a scale of temple runner to final fantasy tactics, this game is junk jack x.
On a scale from 1 being an A and 26 being a z this is a 2
And on a scale of Mario items, this is a fire flower.
Overall a 96% in type of game.

Awesome game!

I am on level 37 and have not spent any money! It can take some time to expand and build more of the higher priced things but if you’re patient you can do it. I havent been playing that long. Maybe 2 months or so and I have 2 islands unlocked one of them being almost completely utilized. I love it. I especially love that I don’t hAve to farm and sell and all that other annoying stuff that other city building games require. The commercial building generate money on their own. The key is to get them upgraded at the highest level quickly so that they are earning the most as possible. Anyway... great game!

Suggestions for improvement

Hi. I really love this game. I have been looking for something similar for a long time. I enjoy playing it. However I have a few recommendations that would be nice to have.
1. I wish we could have options for building infrastructure like airports, train stations. Those would be cool along with animations of planes taking off and landing.
2. It would be nice to have power plants such as nuclear, coal, wind mills, solar farms, hydroelectric dams. And then having some challenges like bad air quality because of too many coal power plants. Or residents complaining because of dense fog due to pollution from coal power plants. Getting more happiness points for having more wind and solar farms but the up front cost of wind and solar is more than the coal.
3. Having more options for commercial buildings such as gas stations, grocery stores, factories, banks, etc.

Thank you for making such a wonderful game though.
