I Knew It!: Many fans have correctly guessed that Madeline was transgender thanks to the ending of Chapter 9 (Farewell) implying it, before it was later properly confirmed by Word of God in November 2020.
Limited Special Collector's Ultimate Edition: The game received a physical Collector's Edition for the Switch and PS4 versions, courtesy of Limited Run Games. Along with the game, it includes a steelbook case, the soundtrack on a cassette tape, a patch, a postcard, a poster, a sticker sheet, a stuffed winged strawberry, and a strawberry pie recipe.
Word of God: The monsters that chase and attack Madeline in Chapter 5 are unnamed in the game, but were officially named "Seekers" during a speedrun of the game at SGDQ 2018 that was commented on by the development team.
