What do you think?

seems more like Undertale Schizophrenia

Gotta be honest, the human soul designs are very generic. They don't really look unique compared to other fan designs. Very color-coded to their soul colors, which doesn't look great when compared with Frisk and Chara(and Kris in Deltarune). I could give some recommendations!

About

"Undertale: Prism" is a solo-developed expansion to the beloved Undertale mod, "Undertale: Red & Yellow", adding on the 5 other human souls of Charlotte, Harry, Sunny, WIllow, and Melody!

This mod is intended for people who have played throughout Undertale, Undertale Yellow, and Undertale Red and Yellow.

As this is a mod, you WILL need to have the original Undertale game installed. Due to a mobile port being piracy, we will never provide an official one.

If you do not know how to mod Undertale, please watch this video.

F.A.Q

Q1: "Can you add ___?" "Why isn't ___ the ___ soul?" "Where's ___?"

A: This mod features original takes of the human souls, and will not be changed due to how far along the writing and progress of the mod is.

Q2: "Where will the demo end?"

A: The first demo ends at the start of Hotland! The next demo, however, is predicted to end around New Home.

Q3: "Did you really get Shinix's permission?"

A: We did!

Q4: "Where's Sunny?"

A: The souls appear as you get near their items, and so with this, Sunny will not appear in the mod until the next build is released.

Q5: "You specified there won't be a mobile port, but how about any language translations?"

A: We don't plan on making any ourselves, but you can make fan translations!

Q6: "Can I join the modding team? Are you hiring?"

A: The mod itself will remain solo-ly developed, but thank you for asking!
