The game features an unused sixth hidden tape (marked by a blue cassette shell) called "Herd of Mouth with Wooly the Sheep" that can only be accessed by modifying the game's code in a text editor. However, the tape consists solely of Wooly sitting at a table while occasionally making minor gestures for nearly ten minutes, suggesting that it was added purely to mess with dataminers.

In the original version of Amanda the Adventurer (retroactively renamed to Amanda the Adventurer: Pilot Episode after being picked up by DreadXP to become a full game), Amanda was voiced by Chelsea Lecompte due to the game having to be made in a single week as part of "DreadXP's Found Footage Jam" and being easy to cast as she lived with the main developer. When the game was picked up for full funding, it was decided to recast her in favor of Blair Greene-Osako, as Amanda was a black character (something proposed during the design process) yet was voiced by a white actress in the game jam version. While they felt it was acceptable at the time given the circumstances, they decided to recast her with a black actress once those circumstances had changed. Despite this, Lecompte does still provide voice work for the full game, specifically as the Say n' See toy and Gret-chan the doll.

Skip and Chip, the main characters of Chip's Tips (a point-and-click FMV game released as part of Dread X Collection 3), make a cameo appearance at the end of the hidden red tape as part of a commercial break.
