About Button Down: Lost & Found Pack
Two 40-minute chaptersThe base game's chapters run 14 to 22 minutes. These two reach their boss at 36 minutes, with the boss fight after that. They are not just longer. The difficulty is rebuilt in four bands — easy to 10 minutes, average to 20, hard to 30, then a steady climb.
