Kirbymastah here. I'm a huge fan of Majora's Mask speedruns, since it's one of my favorite games of all time, and I'm very glad to finally see one of my favorite zelda categories to be speedran in a GDQ! Put this donation to thiefbug's choice, I've been watching his streams very regularly and he's one of my favorite runners to watch!
Good luck to all four runners! Let the dampe luck be with you!
Also, I'll donate another $50 if you get the postman minigame first try. Hopefully I'll be awake by then...
