Jevil didn't have a playlist for his songs yet, so I went ahead and organized one!

If you haven't already, be sure to check out and follow him @jester-devil!
He's made some amazing tracks so far :D

(And thanks a bunch to the creator for the awesome content! Best wishes in completing the rest of the OST!)

JEVIL DELTARUNE IMPRISONED OST

Slick's Top 5 AU Fanfares

This is the "Fanfare" replacement

This is a Deltaswap take of mine and it is not for your AU. Please do not claim it as yours, although you are allowed to extend this song, provided you give credit to the original creator. Ask beforehand.

Introducing "PROSEMOOR". A complicated opposite of Deltarune itself. It's named that way instead of an anagram of Underswap or simply Deltaswap. The relevant swaps for now are listed below:
• Asriel - Kris
• Alphys - Toriel
• Noelle - Susie
• Rudy - Asgore
• Frisk - Ralsei
• King - Lancer
• Rabbick - Rudinn
• Bloxer - Hathy
• Seam - Jevil
• Puzzle Guy - Clover
• Starwalker Bird - Scissor Dancer
• Ponman - Jigsawry
• Malius - Top Chef

• Empty Town - Card Castle
• Scarlet Forest - Field of Hopes and Dreams
• The Cliff - The Great Board

Whether Deltaswap should exist or not at the moment. In the end, this is just a fun little project I'm making.

[Deltarune AU][PROSEMOOR - Fanfare] Fanfare

DELTARUNE Chapter 1 (Original Game Soundtrack)

Fanfare (from "Rose of Winter")

Fanfare (From Ashes to Dust)

*King joined the party!
*...
*King left the party.
I don't know how this replacement works lol
Deltarune: Dark Mode is a Deltarune AU where the Dark World switches with Light World. This includes characters and places as well.
So uhm to explain what this au is it's basically just a swap with the dark world and light world places with some SOL(SliceOfLife) elements. 
That’s probably disappointing to some of you but I don't know what you expect from me I'm a noob -\(:/)/-.

(btw these are just concept designs they’ll probably look different.)
