It has an interesting and different idea. For the limited graphics, the intro is a nice addition to give you the setting for the game. The gameplay with the mouse is a bit clumsy in how you have to use it to both select the topics and aim at the customers, but on the other hand having keyboard keys assigned to the topics wouldn't be so easy to learn maybe. Having more topics and people on each day is a nice way of adding difficulty. Overall, it seems promising for a work-in-progress.
