- Actor Allusion:
- Manny is voiced by Wallace Shawn, and like his character in The Princess Bride, he relies less on brawn or speed and more on wits. The very final trial is also lifted directly from the movie, including goblets filled with a certain poison (non-lethal in this case). In Chapter 3, if you get caught in Manny's hideout, old Graham will call it "Inconceivable!"
- Richard White, who voiced Gaston in Beauty and the Beast, here portrays Whisper, who's about as full of himself as Gaston himself was. Graham will even comment that he looks like a Gaston.
- The Merchant of Miracles' relationship with Mr. Fancycakes is very similar to a certain king and his penguin.
- A couple of Back to the Future references appear, in homage to Christopher Lloyd (Old Graham)'s role as Doc Brown; the most obvious is in Chapter 1, when Old Graham mentions Regulation One-Point-Twenty-One.
- Two different chapters have a scene where Graham falls out of sight, only to come back into view standing triumphantly on a moving platform with his arms foldednote , mimicking the scene from BttF2 where Marty jumps off Tannen Tower, then reappears standing on the hood of the Delorean.
- One of the ways Graham can die in Chapters 3 and 4 is by freezing to death, and while it isn't specifically referenced in either chapter, it can be assumed this was intentional.
- Name's the Same: Don't confuse Princess Neese with the high priestess of Marfa or her granddaughter.
- Refitted for Sequel: A section of Chapter 5 consists of some ideas that were developed for earlier chapters (according to some concept art) but cut, among them a goblin riding on a rat and an entire song by Whisper. They surface here when old Graham becomes confused about the earlier stories he had told Gwendolyn, with her correcting him on the details as a meta-commentary (she literally says that the Whisper song, in particular, would've "made that chapter too long").
- Talking to Himself: Royal Guards #1 and 2 frequently talk to each other, and they're both voiced by Gideon Emery.
- Troubled Production: According to some leaks and accusations from the Homestuck fandom, The Odd Gentlemen stole funds from the Kickstarter of Hiveswap to make this game, which led to a falling out between Andrew Hussie and the company, all further development of Hiveswap being done by Andrew Hussie's own company What Pumpkin rather than The Odd Gentlemen, and the Schedule Slip that Hiveswap suffered afterwards.
