I don't know why people are complaining about this game using Unity. Unity is a lot less likely to crash that Flash and doesn't lag at all like Flash, and unlike in the past it can now be run on Linux with the Pipelight add-on, so it is available on every major OS.
I just completed the game. Here are a few tips. First, there are only 3 cities you will be building in if you are wondering how long the game is. Second, it is better to assign cleaners and guards to specific floors. Third, upgrade the booths to reduce the chance of being robbed AND to reduce electrical problems. This will allow you to only need a few Technicians which should be set to any. Fourth, build elevators so each one only reaches 2 floors, and use two columns for placing the elevators to create a step-like formation up the building. Fifth, you should not need more than 8 floors for any of the missions, including the New York City one requiring $250,000 profit in one day. In fact, having more than 8 floors will start losing you money as shoppers will spend more time traveling than actually going to a store. Enjoy the game!
One tip I haven't seen is to start each game off by moving your city to a high elevation if it starts off at a low elevation. Then just follow everyone else's tips and people should find this game much easier.
It's to bad Flash Player has changed over the years. Games that used to work perfectly fine years ago in an older version of Flash Player start breaking with new versions of Flash Player.
This game's mechanics are great, but it is all but destroyed due to the lag. Only rarely can I play this game without having controls respond less than 5 seconds after I do something. So unfortunately, instead of 5/5 Stars from me, this game only gets 2/5 Stars due to the severe frustration due to lag.
Bleh, all the grammatical errors in the game just by the time I've reached the Select Race screen has made me decide not to try this game. PLEASE get an editor or double-check your writing.
Small in-game typo. In the 3rd route 2nd stage "Transfer Cells Blockade" if you choose "Web Shooter" you get the fail message, "Your hands are still covered up you know.", and in small print below that is says, "Can you even shot web?" instead of "shoot".
