Cold and Flu Invasion
To see what color of HALLS drops are inside each drawer, hover you mouse over the drawers.
To toss a HALLS drop to a sick customer, click the drawer containing the right color and then click on the customer.
When customers start sneezing and coughing by the counter, your thermometer will rise and you will move less quickly. If the thermometer reaches the top, it's game over.
If you see a red light on the counter it means you're out of drops in that drawer. To refill, just click the Refill button and then the drawer you want to fill.
If you pick up the wrong drop, just toss it in the Halls recycler.
