IF - Underfell
Welcome to Underfell.
Play as a customizable "Frisk" who has fallen into Mt. Ebott: a mountain that houses a kingdom of banished monsters. These monsters resent and distrust humanity, most will attack any human on sight.
You have no way to climb back out: you can only move forward.
The story:
Long ago, two races ruled over Earth: HUMAN and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell.
This was all part of your history class.
There are multiple monster kingdoms, although only one in your country—as far as history is aware—and where exactly they are sealed no one knows. One of the many mysteries lost to time.
Or rather to war. Specifically the Great War which took its terrible toll on humanity. Since sealing the monsters centuries ago fewer and fewer humans are born with the ability to use magic. The Great War nearly wiped out the rarities that remained, and since the war, no other human has been born with the ability to use magic.
Which is truly a shame as the world is still filled with magic.
Humanity is coping as best can be, but it is not an easy transition. What countries remain after the Great War are largely dependent on magic; switching to an alternative power source has been a struggle.
The last humans who can use magic are struggling to keep up with the demand, and their aging bodies only signal humanity's time limit.
You, like most of the population, cannot use magic.
But that’s okay!
You don’t need magic.
You have something else. Something even better.
You have you.
The romance (OPTIONAL - platonic / friendship routes are available):
- MAJOR - Sans (M)

I translated the language of entity and it says I have something. Something I want to show you
GRILLBY 4 LIFEEE AIDHFIAFNAISFNAS
oh my god I just went spicy for him instead of sweet
IM GOING TO CRASH OUT FSNSUNSDIGNSDNSDIGN
DAMN RIGHT I AM!!!
Sans route- WHAT DID I DO WRONG WHYD I LEAVE AND FORGET WHYYYYYYYYYY
Darkpetal I'm cryingggggggg
hi, im guessing this was made in the harlowe format??
I have finally completed every route in this game... At least, every route I know of. It was gorgeous. I loved every second of this. My favorite routes in order were:
Wingding's route (He's the best skele. Hands down. No competition. The "It's quiet without you" line was what sold me for good.)
Harem route (All the skeles including the best boy. Very happy with that)
Papyrus' route (Sans might've stood a chance if he weren't a trash goblin. Besides, Paps is just so- Agh! He's adorable. The tag-teaming was the cutest thing I have ever had the pleasure of reading through.)
Sans' route (Super cute. Minus my 69 deaths. Bonus points for the funny number. More bonus points for the puns. My sense of humor is terrible, and he's terrible. A match made in hell lmao.)
Grillby's route (Not an inherit fan of him, but I happen to have a weakness for hot guys telling me I'm a good girl lol)
Asriel's route (Friggin adorable. Super well written. Buuuut he's a bit too sweet for my tastes as a character in general... Perhaps I just have bad tastes)
Friendship route (It physically pained me. You know how hard it is NOT to smooch ANYONE? Still was super cute though lol)
Sirentale, here I come >:)
I salute you
Man I had to go back to snowdin to get that stick- at the lab- the answers changed???
So cool
edit 1 : I realized even after I reset it (Like just a full game reset)
My relationship answers for flowey are missing- maybe I picked some wrong answers but I dont know (not going for him anyway but stillll)
Edit 2 : I made it to the core/city...
IT CHANGED THE FIRST TIME I WAS WITH GRIBBLY?? I WANT MY SEXY FIREMAN BACKKK
WHAT HAVE I DONEEEEEEEE
Edit 3 : Could the game be mad I reset it fully..
DO THEY KNOW????
WHAT DID I DO WRONGGGGGGGGGGGG
Edit 4 : WHY NO MORE SEXY FIREMAN
WAAAAAAAAAAAA
sueing /j
Edit 5 : My MTT bit has changed completely I Dont understandddd
Rizzed up sans
i can't get the romance route for sans, i'm going to lose it- i got the true friendship route and normal friendship route- sobbing crying
Is it just me but when I load the music just doesn't play?
Edit: Fixed it 💪💪💪
I need some help because I reached the end of hotlands, but it won't let me move on.
For mobile the music selection and help isn't showing up
(༎ຶ ෴ ༎ຶ) me rn because I never saved my saves to a disk (also super cool for this font to be like this (・∀・) )
But at least this is now a good reason to replay! ( ´◡‿ゝ◡`)
i dont mean to sound as if im complaining, i LOVE all your Undertale stories!! But is there a way to make this like, full screen for a phone? This new visual update is great!! But at least for me i have to put the text soze to 200% to be able to read and then i am only able to read 3 lines at a time, gods i must sound ungrateful! I dont intend to sound whiny or anything, just asking. Sorry if this comes off as rude, i respect you so much!
Guys I need help how do I get gasters romance route because I have zero clue
uh, when i prayed to the graves, i got a locket, and later i went to the secret labs and grabbed the file that had gaster's work on it, and later in the throne room or something you get the option "you hope you see wing ding in the locket" when you open it up, and it automatically locks you in for that route
XD welp here i go again time to jump back into underfell its been a while since I yelled at UF Sans. Going to do a full revisit playthrough to think this was the first if game I played so happy to see it get a visual update. Cant wait to upload more of it to the channel
Not gonna lie I was playing Delta traveler and one of the boss fights With Underfell sans and I was constantly yelling at him I still love him though
LMAO
Oh boy, an excuse to replay this game again! Don't mind if I do!
Ok so, I made Shyren sing deez nuts as a joke. AND AT THE END WHEN SHE DID IT AGAIN? Freaking hilarious because I had forgotten about it. Love this game btw!! All of your games are so amazing and unique, have a great day/night, and be sure to continue with your games!
i got a funnier one for you. (or, at least, it's funnier to me.)
try putting the entire "Number 15: Burger King Foot Lettuce" copypasta in... both times that it gives you the prompt.
I have never played undertale, but this game makes me want to. I got the neutral ending and actually might have teared up a little when I forgot Sans.
I think the routes could be fixed... I mean, there could be a genocide route, or maybe while the player is on a genocide route, we could be romancing with a character. It would be fun and exciting to see! (For example: while the player is on that route, they could be romancing with Sans). And it could be improved a bit when the player reaches Snowdin and is romancing with both skeletons (Papyrus and Sans). I say this because when I did it, the route was very short and... it was something I didn't expect. But despite that, the game is entertaining!
tbh, i would like to know what program(s) you used to make this game, not only is this one of my favourite AU games you've made and i just ADORE it but i would also like to make my own games like this too ^^ <3
Yall I made Shyren Rick roll the entire marshlands lmaooo
I keep playing these games every time I feel down, the writting is just so good and the story it self is so interesting, I absolutely adore your work <3
i was never interested in undertale fan games before, the keyword being before
this is so, so beautiful, and made me cry a few times
your writing is incredible, i'll be checking out your other works (and also re-playing this one, got two routes down so far!)
"Aishite Aishite Aishite" is a good summary of my mentality playing through.
what does flirting with napstablook that last time do? i’ve played this a couple of times and i haven’t figured it out
Why aren't the voices working for me :'(
they were removed from the game; voice actor did some ,, unsavory things
oh damn :/
i love the game SO MUCH!!!!!! although im stuck on the part where you see the nice cream guy for the first time in hotland, it just wont progress no matter what i do :(
Amazing game! <3
I am so happy to see that there's so many! (Most excited to play Underswap <3)
!SORTA SPOILERS!
For the sick Papyrus bonus scene when we text WD and Sans it's bold except for WD it becomes regular italics and the text after that is bold.
If that's intended feel free to ignore this.
I love this game. The first time I played one of your games, I stumbled into it by accident, but they're the best thing to binge. Also, the "are you okay" was so wholesome. :)
I really like the game
Sans has been really cute
I think you done a great job each time
You're feeding the fans really well but i do have a question or two.
The audio in the game sometimes loops and i can't seem to hear the voice acting. Is there a possible solution to that?
Many thanks! I look forward to your other works and progress ⭐
help I think I’m in love w/ Grillby :(
So I usually don't leave comments/reviews on games or comics 'en things but I just cound't help it this time THIS GAME IS JUST SO AAAAAAA!!!! I'm gonna cry from excitement I just finished the game for the first time (I wasn't sure what route I was gonna do first but ended up doing gasters rote and I just turned to mush!!!) and I'm absolutely blown away by how good it is and can't wait to play more, that coupled with the fact that I've been trying to find more undertale games on itch.io too, and that I fond this game throw the tumbler blog is even better in my book, all in all this is an amazing game and I'm totally going to check out the others by the creator even if their not all completed yet!!!!!
i literally created this account so i can tell you how much i love your content and have grown up with it as time has passed. i honest to god cannot explain how much your writing means SO MUCH to me and has been one of my pillars to why i write myself. from your fics to even little gems like this, thank you for distributing your works of art.
ENDING I GOT INITIALLY - TRUE ENDING (GASTOR ROUTE)
ENDING I SETTLED WITH - HAPPY ENDING (GASTOR ROUTE)
because gastor never fails in making me a mess and i should've honest to god be working on my college assignments atm LMAO ♥
I can't find the stick-
You gotta leave Snowdin immediately after Sans bring you there when the game gives you the option to explore. This gives you the Greater Dog encounter which'll give you the option to get the stick when you spare em
Oh alr ! Thanks ^^
I made an itch.io account JUST to comment on here. I. LOVE. YOUR. CONTENT!!! I got hooked immediately on your WIP Horrortale, and as soon as I finished the Ruins section, i played Siren Call to completion. Ugh, the story? The WRITING??? So much better than I could've hoped for. These interactive stories are so well-written and in-character, and as soon as I finish all the routes in Underfell, I'll be playing your other games as well. Idk what future me will think of the other games, but current me has decided that your Underfell is My New Comfort Game!!! Sure, there's a lot of death and gore, but there's something so feel-good and comforting about how you write this AU. "It's not Kill or Be Killed, it's Save or Be Saved". Beautiful!!!! That combined with the classic Undertale music, and the fact that there is no genocide route?? UGH! Instant cozy game with happy good feelings. From the bottom of my heart: thank you for making these, and I really look forward to playing the rest :)
