The project introduces a reworked gameplay mechanic based on both UNDERTALE and DELTARUNE.

  • A reworked UNDERTALE's Battle UI.
  • New Spell Learning System.
  • Puzzles and SPECIAL STAGES!

All the monsters can be "beaten" throught non-violent interactions. Observe, understand and respond according to their personalities and preferences, there is no violence required for every encounter.

Just like in UNDERTALE & DELTARUNE's battle system, dodge the bullet patterns to survive. Remember that if your HP drops to 0, it's GAME OVER.

Enemies might alter their attacks mid fight, so keep an eye out for the changing patterns!

UNDERPALS' combat is designed to be reactive, memorable and dynamic. Make your choice, traverse your own path, and discover the narrative weight of your actions..
---CAST---
HUMAN
(The Human.)
Human character GIF
The HUMAN is the protagonist of the story, the only one you will guide until the very end of your journey.
(If you are asking, no, they are not drowning actually, it's how they were born.)

They are a simply observer, shaped entirely by the choices you make during your walkthrough.
(Fun Fact: the HUMAN smells like wet lavender.)
RAGEL
(The... Mushroom?)
Ragel character GIF
RAGEL is a…FRIENDLY FOE, SOMEONE WHO WILL ABSOLUTELY STAY BY YOUR SIDE AT EVERY MOMENT.

SOMEONE YOU CAN WHISPER YOUR MORE DEEP SECRETS. HE DEFINITELY WON'T HURT YOU.

He only asks for one simple thing: OBEY HIM, DO NOT QUESTION HIM, TRUST HIS WORD COMPLETELY, after all, he's not going to hurt you…

Never...Right?
AVELINE
(Kind old lady.)
Aveline character GIF
AVELINE is a peaceful and compassionate monster that spreads respect and empathy wherever she goes.

She is a servicial monster, always ready to help those in need. Loves cooking, tending her garden and assisting with social services in ASTLALOT, she finds hapiness in supporting her community.

Sometimes she can be a little overprotective, but her intentions come from her warmth.
SERIF
(Papyrus son.)
Serif character GIF
SERIF is a member of ASTLALOT monsterkind population, living with his uncle SANS.

He is a technology enthusiast teenager, building and modifying devices, trying harder to become a Royal Scientist.

His enthusiasm and eccentric personality sometimes can overwhelm others, making social interactions complicated. Making new friends is not one of his strongest skills.

Besides the exaggerated speeches, he won't seek destruction, he just want to prove himself.

DEVLOG

UNDERPALS game logo
Pre-Development Phase
In 2022, UNDERPALS started as an UNDERTALE parody webcomic. The idea was really simple: use UNDERTALE's original story, featuring characters from other franchises and also adding a twisted version of Frisk as the fallen human.

At some point, I considered replacing Flowey with a fish-like character, but then I decided to use an UNDERTALE side character: Ragel. This choice was mainly inspired by different projects such as Moonster's UNDERSWAP take and UNDERSWAP: Salt & Pepper.

Concept Art
Fun Fact: Serif was originally supposed to be a fusion between Papyrus and Sans.


Development Phase One
After spending one year without progressing beyond the first comic panel, I changed the project’s direction. In late 2023, I developed an UNDERTALE engine on Scratch.

At first, this engine was meant to be a completely separate project from UNDERPALS webcomic. However, I quickly saw its potential and I decided to merge both ideas.

Initially, it would be "An UNDERTALE-like experience" where characters from other franchises replaced the originals, but over time, this approach started to feel creatively limiting. Trying to write dialogues without mischaracterizing existing characters became frustrating, that's why I decided to make a change.

In mid-2024, I began introducing original characters. For this moment, progress was still slow, but it marked a straight direction for the project.


Development Phase Two
At this point, most of the ideas for UNDERPALS were finally established. Characters like Aveline, Serif and various NPC were added during this phase. Script was rewritten from scratch to ensure a better narrative coherence and consistency.


The human protagonist, Otto, has a design, mainly inspired by UNDERTALE: Comet Trial, particularly its use of unusual colored skin tones.


The lore also evolved significantly to improve storytelling on this new version.


In UNDERTALE, the player explores the Underground and during their late journey, they confront King Asgore. In UNDERPALS, however, the story takes place in the "Otherground", a deeper layer beneath the Underground, where monster populations are against its king.


Additionally, UNDERPALS features more than just two races...but that's something I'd rather not reveal yet!




Current Progress & Next Steps
The UNDERPALS demo is currently about 55% completed. The game engine is fully functional and development is now focused on:
  • Completing the route system.
  • Enhancing battle mechanics.
  • Fixing minor bugs.

    • From my point of view, the project is going far well and I don't expect it to take more than one year to complete.
