"DELTARUNE: Life Advice" or "mY AWES;OME DELTARUNE THEERY*", is a long, dense analysis of DELTARUNE Chapters 1-4 that I started sometime in June 2025. I don't know if it counts as a "theory" since I don't think I'm trying to prove a hypothesis (or maybe that's just me being arrogant.....). I aim to meet the game where it's at from a Doylist perspective. I consider my approach to be more like literary analysis, except worse because I'm not very good at it.

As per the name, my primary goal is to understand what Toby Fox wants to say. UNDERTALE had defined messages, so what are DELTARUNE's? I believe that, rather than being intentionally opaque, DELTARUNE's thematic makeup has been consistent and clear since at least Chapter 2. Things like the secret bosses, the Knight, or Darkness aren't meant to be hopelessly enigmatic; they've always had a purpose.

Very little of this is "new". Maybe I've arranged the pieces in a slightly novel way, but it's basically just an iteration on THE DEVICE THEORY by mollystars in light of Chapters 3 and 4. The final section of the document has a more detailed list of people I graciously stole from.

This document aims to do the following:

• Treat DELTARUNE as an intentionally crafted narrative, rather than as a riddle.
• Understand the narrative and symbolic purposes of Light and Dark, hopefully culminating in a solid foundation to tackle other elements of the story.
• Convincingly argue that DELTARUNE is about stories, conflicts, endings, and the people involved.
• Draw from Toby's previous writing and inspirations (+ some other crap I like) to strengthen my case for the above / better explain my thought process.

This document will feature:

• A reading of the final Prophecy that fits the themes of the game first and foremost.
  • Beyond this, not a single attempt at predicting what "will" happen or "how" anything will happen, but a look instead at what has happened.
• The mindset and desire the Weird Route speaks to / critiques.
• The role of the Shadow Crystals.
• Why W.D. Gaster is still at the heart of the game. Wait Where are you going come b
• Thorough analysis of Carol Holiday.
• Thorough analysis of December Holiday and "Raise Up Your Bat".
• An answer to the question: What does Toby Fox mean when he says "don't forget"?

The whole thing is 164 pages. I don't recommend reading it in one sitting unless you truly have nothing better to do.

If any of this interests you, please refer to this page to read it. If you have questions or would otherwise like to discuss the document, feel free to send an email or something. I'll try to respond as soon as I can. (probably pretty quick since I do jack shit with my time)

I've been working on this for several months, and thus will only update the document if something truly groundbreaking or showstopping comes up. The rest, as they say, is up to you.

It's not really all that special, but maybe you'll find something worthwhile.

Thank you for your time! ^-*
