I love the Binding of Isaac! My girlfriend has watched me play the original game for over 100 hours, and now we play it co-op in Rebirth. It is one of my favorite games, so I wanted to pay tribute to the series, as well as to Edmund McMillen for creating it.
Thank you Edmund for making such fun, frustrating and addicting games that I will never forget. And thanks to your creative efforts, you inspire me in my own pursuits. You rock Edmund!
