Met a guy on my way through the desert. He showed me where to find the glowy runes that I kept missing, and I showed him some better jump routes that I found because he had a shorter scarf than me. We used the sing button a lot, we both hit it a lot when surprising stuff happened or we wanted to get each others' attention. It was honestly a little bit magical.

On the credits screen, it revealed that his username was "shartman1987" and I can't decide if that made it more or less magic.
