CHAPTER 3:

Dustpiles returning

Spilling the subtext beans way too early. (Ralseis first big thing is explain lore talking about reality and stuff)

Misplaced rudinns? (Just like starrune shopkeep rudinns)

Old video games. The old console being an important part of the dark world.

Battle where you can only act (roulx card chapter 3)

Susie talking the boss down after a battle.

The main villain wants to create an everlasting world.

Ralsei being all like "Please forget and move on from fiction."

Flower brings money!

Unlock ability to cross water (raft)

Single screen moves between slides, just like monochrome mod 1!

Part of the world becoming monochrome! (Towards the end of chapter 3 and like the monochrome mod)

More acts with different TP costs!

Monochrome Mod shopkeeper was on the money with her being like "you didn't meet the knight yet but Kris might" with it likely being Noelles mom or sister.

Like Kris knowing the roaring knight even matters. She was VERY correct.

Susies Heal getting better. Literally called Ultra Heal in chapter 3

Regular object being treated like a super epic fight. (Water-cooler) (tree)

The pipis is over world only food like the watermelon from starrune

CHAPTER 3 SECRET BOSS:

Secret boss taking place after the regular final boss.

Both secret bosses are "destroyers of worlds" (roaring knight causes the roaring) (apani is a death deity thing.)

Fight only boss you can't beat but only harm that is like super deadly lol

Needing to beat a secret boss to obtain equipment that allows you to reach the secret boss.

The secret boss conditions affecting the ending of the dark world.

The chapter 3 secret boss can't be checked. (In DR, it doesn't reveal anything, in starrune the option isn't there.)

In universe nod to the weird route. (The lost library snow game forum room.)

Even doing a mercy run things get "weird" (The sword route being weird) (Apani being spared using snowgrave)

CHAPTER 4:

Noelle ignores telling her mom to do stuff with Susie.

Minigame from third dark world appearing in Castle Town. (The arcade cabinet from starrune)

Ralsei having an empty Minimalistic room

Nubert cult talk? (Nubert is part of everyone, kinda like a god.)

Dark Library! OMG, the lost library predicted the church dark world.

Act only party member. (Old man chapter 4.) (Noelle in cinnamon clouds)

Susie having a mentor (apani did teach bee buster)

There being more combat required fights

Susie creating a dark world 

Final Boss fight against a giant.

Special soul mode appearing after their secret boss. (Green soul gerson statue boss.)

Special armor that raises nothing but a single stat.

You fight smaller versions of the final giant boss before fighting the giant final boss. (The fountain babies) (The pre apani fights)

Climbing has a speed mechanic that is lost on touching a wall. Like the starrune speed stuff.

Simple Adventure sounds kinda similar to from now on, the second regular battle theme of deltarune.

Chapter 4 is about the legend of the deltarune, the lost library is about the legend of the starrune.

CHAPTER 4 SECRET BOSS:

Difficult Susie only boss for a hammer 

Axe that heals

The secret boss is the mentor.

Green Soul.

CHAPTER 4 SECRET GIMMICK BOSS:

Castle town having an exclusive boss fight.

Allowing the player to return to castle town from inside the dark world.

WEIRD ROUTE:

"This sure is a weird route." -susie in both Starrune weird route and chapter 4.

THOUGHTS (OLD):
Chapter 3 could easily be explained with "Um since Susie created the Dark World of course her version would not feature the TV lmao."

Chapter 4 is actually much more on the mark lol, a dark library, a mentor figure for Susie and a dark world created by Susie. I guess this game being a Chapter 4 AU at first now has its pay-off.

Although I did get Susie being like "An eternal world is bad actually" wrong.

THOUGHTS (NEW):

I think the reason I am so accurate is because I did what Toby did in a way, instead of making Chapter 2 2 or predicting what Toby would do I decided to try and evolve Deltarune. I admit a lot of this is coincidence but I am still happy with how it turned out.

Still sad that the "Purple No" thing didn't come true. I thought I had that one in the bag.
