Busy Corp Computer Game

I am planning on creating a computer game that is as user friendly as possible.

The objective of the game is to build and manage vertical transportation systems to help the members of a building get to their offices faster so that they will have more productive hours at work.

Here is the half made skeleton of the prototype that has been made so far.

GUI Skeleton Implemented so far.

Please notice that I am planning to have construction buttons on the left that allow the user to build structures. The boxes in the middle of the screen will represent different objects in the game including offices, elevators, ladders, doors, etc.

Below is a design sketch of my current visual layout decisions.

Here is a design sketch from several weeks ago. Special events that I plan to incorporate into the design of the game include the morning commute, lunch time, maybe fire drills, and the evening commute.
