I love this. The concept is so simple but so complex. It's two strangers in the apocalypse talking in a car, but it's so much more than that. While I do wish it was longer, I love the endings as they are very open-ended and let the reader decide what happened after the ending. It interacts with the audience by not giving them a solid finale, and I say kudos for that. To create such a powerful game in only four days? Incredible. Words can't describe what I'm feeling right now.
Job well done. Highly anticipating your next game, if you are going to make another. :~)
