This project was inspired by the biggest theme of the year 2020—**COVID-19**. It is an invisible enemy that humanities struggled to fight against. The U.S. is surely losing the war on COVID-19, but it did not have to be this way. If people are more aware of how they could be infected by the virus, and understand how to protect themselves, then the pandemic would be more under control. I wanted this program to be educational and relatable to the player.

In my program, the players need to actively engage in using three different **tools** to protect the character from the coronavirus for** 80** seconds. By applying the mask to Sam’s face, you could protect him from viruses that are spreading through the air. By sanitizing the table with disinfectant spray, you could prevent viruses from getting attached to Sam’s hand. However, there might be a few viruses that survived or escaped from the spray, so you need to apply hand sanitizer constantly just in case Sam starts rubbing his eyes.

If I had more time, I probably will explore how to parent the virus to the hand once it is attached. I would also like to make the background and surrounding more like a public space where other characters are also involved in this interaction.
