Ruins Theme (demo)!

Visit Original Link

It was probably the first theme i had in mind since we begin the project but i'm still working on a more "complex" version. This is a really short one, it need bass and even a second melody but i want to post the "elaborated" version when i will be totally satisfied ! The Ruins (in-game) will be similar to its peer, the biggest different is Asgore living in on both game., this is why the place is also a "Garden". More flowers, a river and new monsters in there !

Fall Fields Theme (WiP)

Visit Original Link

I tried with a 8-bit soundfont ! Of course it's not finished but i wanted to show it to have at least advices or opinions! The Fall Fields will be the second place after Ruins (so) instead of Snowdin! While Snowdin had more a xmas vibes, the Fall Fields will have a pumpkin-Halloween "aesthetic" with a new mini-boss. Don't worry, most of Undertale's iconic characters would be there ! (Undertale by Toby Fox ofc!)

New Background

Our background! It will be on our title menu we're working on ! The Left is for SwapCultAu and Dttrio on the right ! For the context, These two Univers are a "mirror" of the other (one is a "Swap" of the other, similar to Underswap's concept). We want to create 2 games with the same base but a very different stories, unique yet inspired by our love for Undertale but you'll see references to others video games you may know as well !

I found this meme trend very inspiring, so I decided to join and tell my story as an 2D animator, starting with Macromedia Flash MX 2004, trying stop-motion, to currently working with Adobe Animate CC.

Hoi! After a loooong break I'm finally posting a redraw of my two prota : Alo (Aka Frisk, the first human fallen, and Chara's guide into the underground) And Chara (8th human fallen)

REBOOT

Hey guys It’s not a big deal ‘cause i didn’t post so many things but here come a reboot : -1. New name “UNDERSWAP CULT” -2. My Frisk become Chara (i updated this actually but the stripes still here.)

UNDERSWAP CULT or SwapCult (simplely) is my own version of the Underswap (created but PopcornPr1nce) :  I keep my story, but there’s some new things (i didn’t explain my story so it’s okay).  Next will coming later ! 

[kira-the-trex]

A Speed digi-drawing of my protagonists !

It's Lone (left) and Chara! (Right with Frisk’s clothes)

Lone fell ten years(~2110) after Chara(still in ~2100)! So Lone is the eighteeth human, but 'cause of amnesia, they have the Soul of Purity. They have an half of Chara’s soul to have save.
