Solid concept, could use bug/typo fixing and extra
Some glitches have occurred involving the elevator and employee animation, but otherwise, this game is solid and enjoyable.
I have some suggestions (that others might have brought up) that can improve the game:
-Include more variety in shops and restaurants: shoes, leather goods, athletic apparel/goods, pizzeria, bistro, etc.
-Consider requiring the player to construct more than one booth of a single type. For instance, the visitors might demand a second or third clothing booth. Also consider allowing the player to horizontally (and, perhaps, even vertically) stretch a booth to increase capacity and meet customer demand. Each booth has a minimum size requirement but does not have to come in one size only.
-Allow for construction underground. The price building underground might differ from above ground but also have its advantages and issues
-Consider adding a parking garage to allow for visitors to drive to the shopping center
-Include other types of employees, such as plumbers and valets (for the parking garage). Also consider requiring some security personnel (or a new employee, a.k.a Mall Cop) to patrol the shopping center during the day to prevent shoplifting or fighting
-Add more levels in various cities, from Anytown, U.S.A. to the major cosmopolitan capitals of the world, such as Rio de Janeiro, Milan, Dubai, Mumbai, Hong Kong, and Sydney.
-Add more disasters beyond the bandits, such as fires, burst pipes, even an earthquake (in high difficulty levels)
-Consider including "scenario" levels: a mall is already built but suffering from some malady: unpopularity, electricity problems, etc. The player is to take over the job of righting a ship.
-Include a "sandbox" level: play until you go broke or reach a certain goal (money, popularity) within a certain time
