The Story: 6 Days to Decide

You are scientist John Pilgrim. You and your team have accidentally created a pathogen that is killing all living cells on Earth. You have six days to find a cure. Every day is a new chance to make a choice, but also one day closer to the end.

Your choices will affect the outcome of the story. You can spend time with your family, work in the lab, or explore the world. There is no right or wrong answer, only your answer. Will you find a cure and save the world? Or will you make peace with the inevitable? You only have one chance.
