The fact they followed the Toby tradition of having that one part of hotland in the trailer for literally no reason is truly great

A lot of fan games are either never completed or just forgotten entirely. However, you have managed to do what many fan game developers couldn't. And for that, I, as well as the rest of the Undertale fandom commend you. Congratulations on this incredible achievement! I already know I'm gonna enjoy this!

I will forever consider Undertale Yellow to be a canonical prequel to Undertale, that's how good this game is.

1:02 I like how at this last part, it looks like Clover is about to fight that enemy, but no, that's how you spare them. By yelling. What a good game.

It's an honor to be here. Since playing the Demo, I have never forgotten this Fangame, and I want to thank everyone involved for not abandoning this wonderful idea. I hope your work can be rewarded 💯💛🤠

I love the commitment to making sure that every Undertale related trailer has that one jump maze in hotland shoved in somewhere.

0:43 Either Clover is tiny, or that apple is large as hell and Clover's gut is now completely destroyed.

i'm gonna tell my grandkids that this was red dead redemption

After 7 years of hard work, creativity, and most importantly passion on creating a prequel that could possibly tie in ends to the original game. We now have officially reached that finish line I just want to say thank you for everyone who worked and was part of the project for finally getting it done Toby Fox will officially be proud of you.

The animation in this trailer is stunning! 😍

Flowey went from "Howdy!" to "Howdy, patner!"

I love how Toby is not just open, but very accepting of fan projects. if he wanted, he could probably work with you guys to make the other colors too. Honestly, that would be really really cool.

This is such a fun game so far! I remember playing the demo back in middle school, time flies 💛🤠

Most Undertale fangames get cancelled after only around a year of being in development, either because the developers lose interest, the players lose interest, etc. I feel like you guys could really teach other indie devs a thing or two, since you've stayed so devoted to this project despite having taken several years to finish. Great job, guys!

Every other soul: has cool abilities and lore Yellow soul: for his neutral special, he wields a *G U N*

Ok but can we talk about how *sweet* is clover hugging sweet corn?

I love the sheer dedication behind this project. The animation really shows how much the community is willing to go far to for a game that impacted them so much.

I am so thrilled for you all! Big big congrats on getting this game out in the first place and I can't wait to play it myself!

The way Clover gets hit in the gut with a giant apple is hilarious. Classic gag!

How's it only been four months? Felt like the games been around as long as Undertale

Finished the Pacifist route like an hour ago…I can definitely see why this game took as long as it did. As someone who wants to become a game dev myself, this is legitimately inspiring. I almost don’t want to play the genocide route just because that ending was so perfect. This game is legitimately on par with undertale, and I commend everyone who worked on it. Genuinely, the best UT fangame I ever played.

0:54 As a vent enthusiast, I am very glad you kept this part of the trailer. Seriously though, this is an amazing achievement. After so many years of Undertale content, somehow a fangame that spans the full story has still seemed just out of reach every single time. But you guys did it, you made the ground and put your hearts and souls into this project. All I can say is, amazing job, to every single one of you.

Of all Clover animations I've seen so far, this one's definitely the best

Okay, so, now we have: • “Undertale” - September 15, 2015. • “Deltarune, Chapter 1: The Beginning” - October 31, 2018. • “Deltarune, Chapter 2: A Cyber’s World” - September 17, 2021. • “Undertale Yellow” - December 9, 2023. Damn, this franchise is getting bigger and bigger with every few years and i loved it so much 😎😍👍!

The release of Undertale Yellow is so important that it crashed the Gamejolt servers LOL

Love how you added the vent puzzle just because it was such a prominent feature of Undertale’s marketing. If Deltarune Chapter 3-4 are still a ways away from being released, then this is probably the perfect thing to satiate the lack-of-content fatigue. I hope everyone who worked on this is proud, because they should be! This is amazing, and I can’t wait for what this team has next in store!

I love how clover just takes a sec to check themselves in the mirror 1:00

For his neutral special,he wields a gun

Good time to enter the Undertale fandom. You guys are amazingly committed and that’s a feat in of itself. I wish there’s was a way to show support besides saying “thanks”. So, thank you for your work!

I played this on stream back in college, it was my favorite of the bunch. I applaud your perseverance through the project, I'm sure it wasn't easy. enjoy the fun that comes afterwards! you all deserve it. ^^

I just realized tjat of all the fallen humans, I’ve *never* seen _anyone_ *ever* debate Clover. Like, I’ve seen more disagreements about *Frisk* than I’ve seen about Clover, and that’s saying something. Normally, there’s at least like 5-10 different competing ideas for each of the fallen humans that get cycled out every few months, but I have *never* seen *any* alternatives for the Yellow soul. Just goes to show ya that all it takes to make a great game is passion, inspiration, hopes, and dreams. You guys really hit it out of the park. That ending got me crying for hours (and also sent me into a deep depression lasting jsut shy of a month where I’d occassionally break into tears and sob over Clover’ death for 3-5 hours). You guys did a great job, and I hope someday soon I get so see Clover once more. Love yal! Yeehaw! 💛

This game took 7 years, this is the true meaning of determination

I just finished it. You guys made me cry 😣It was worh the wait. Thank you all for not giving up on this. You and your team deserves all the money on the world. Thanks.

i played the demo all the way back in middle school and now i'm in college ready to immediately play the full game when it drops. so proud of the team for their dedication over the past 7 years, you've all truly made something special

This fan game is telling the other souls story and how they died, in the photoshop flowey the yellow soul is using a gun just like the player of undertale yellow

This is, by far, the coolest, most faithful fanmade Undertale prequel I’ve ever played! Pretty much all the gameplay, jokes, story elements, and charms feel so akin to the original Undertale here! Although the story itself is non-canon, it feels like it could lead to the original events of the game. It was amazing to play through the game from Clover’s perspective. Thank you, Team Yellow and MasterSwordRemix, for all of your amazing efforts and being able to share this with us!

Man, this is great. I remember playing the demo, what, 5 years ago now? This is one of the only real, full, Undertale fan games to ever come to fruition, and I really respect that. This is truly amazing.

Justice is one of my favourite souls, and this looks stunning! Glad to see that the Undertale fangame community is still going strong and making bangers.

As I watch this in a clover cosplay, I am happy Also: clover is such a cute little silly guy I love him He’s so sweet

I love when he gets hit by the apple!😂

it is actually insane seeing this is finally coming out. def gonna be playing it as soon as it drops, congratulations on the release!!!

After 7 years, it's finally here, can't wait to play this man!! Fun fact: b8bbles (the creator of undertale last breath the musical) today, is his birthday, congratulate him, and i'm telling you this bcuz he created the meme "Blocked once more"

0:59 Clover is so cute when hugging that candy corn

This technically means that normal undertale is just undertale red

Amazing animation

*the fact that after so long this fangame has been released fills you with DETERMI- uhh I mean JUSTICE* *HP fully restored*

Guys It's official Undertale Yellow is now an actual Undertale Prequel It's not a fangame anymore.

You know your fangame is REALLY good when people change the narrative of Undertale so that the humans get resurrected after the pacifist route just so Clover can live, reunite with his friends and have a happy life. This game brought me to tears so many times and I applaud you all for going through with it!

Yes!!! Finally!!! I’m definitely going to be playing this! Almost can’t believe that this game finally came out

You can tell how anticipated this was by the fact that the store page won't even load, presumably due to traffic

I wish this game was allowed to be on steam.

I’ve liked this fan game so much that at this point I consider it a canonical prequel to undertale.

the amount of love and dedication this it put into is crazy

Wow the hype was so huge that Gamejolt imploded on itself.

So,this is what happens when clover dodges an attack.

I like how in this scene it shows the ways you spare the monsters. 0:57

Okay, I'm gonna be real. This might be one of the best, most faithful fan games I've ever played. It is an honest to goodness prequel with so many secrets to find, complete with routes that vary even more than the ones in OG Undertale. The charm is all there, the emotion is all there, the creativity is all there, everything - it feels completely authentic. The polish is so complete that Toby himself might as well have made it at times. On the same token, it brings so much new to the table, and it'd feel wrong to spoil even a crumb of it in this comment because it's all so good and it's all _free._ Props to everyone who worked on this project - as someone who was a freshman in highschool when it was announced and has been waiting since, it truly paid off and then some.

7 long years 7 YEARS waiting since the demo released back in 2015-2016 and I couldn't be more happier with the wait. This fangame is one I have been checking on and I am glad I have. Most fangames I have watched and waited for have mostly been canceled, delayed, or not done. I am glad y'all was able to stick onto this project and fully complete it. Thank y'all for rewarding all of our patience.

Dude I remember seeing the demo YEARS AGO and I was just getting back into Undertale and Deltarune through some play through videos that popped up and I’ve been going down the rabbit hole all over again, AND I SEE UNDERTALE YELLOW LAUNCH TRAILER! Omg congrats! I’m excited to play! Will definitely play it when I get the time, I’m sure it’s AMAZING! Looks amazing ❤

Hopefully, this fan-game will start a new era of undertale fan-games

This sparked a kid inside me. Playing the demo years ago hoping that one day it would be complete, and here we are.

Game so fire it crashed Gamejolt on release.

i love that clover isnt a soulless (haha) kid and actually has emotion

i've just played the game and i have to say, it made me feel something even undertale did not. while starts off as a cute world, very much inspired by ut, at some point it becomes a crazy adventure, filled with heartbreaking moments and a unique, captivating atmosphere. and the pacifist ending - it made me shed a tear. i'm absolutely in love with what you've done.

This project was in development as far back as in 2016, when the UNDERTALE fandom was in its infancy. I haven't been following its development at all, and in a post-DELTARUNE Chapter One and Two world I thought the project was on hiatus, if not cancelled. Welp, guess I was wrong, because you guys pulled through and have finally unleashed your passion project onto the masses! It's surreal to see this fangame completed, and I'm definitely looking forward to playing it very soon. In the meantime, congratulations to everyone involved in the project for making your dreams come true!

Just finished the game. You and your team did such a great job.

I have just finished the game, the pacifist ending made cry, and like that one guy said "i cant believe a couple of pixels made me so emotional" 17/10

I just finished 2 of the game's routes. Honestly up there in quality with Undertale itself. I am blown away that such a faithful yet original fangame ended up being this good, and FREE?! Truly an amazing experience you guys crafted. Loved every moment with it and still have one route left to try!

historic moment in the community we lagged the servers of gamejolt so hard it went down for a while

My god, I never thought I'd see the day where not only a fully original and great Undertale fangame is made but it's actually a full videogame rather than just skipping everything until you reach sans. Beautiful!

I see no sans in this,i think we're in the clear now.

Welp Yellow is definitely bringing the community back.

I'm so glad it's finally here, been waiting so patiently for 7 years. Who cares we broke GJ, I've waited this long, a few extra minutes wont hurt.

This fangame is a breath of fresh air from the au fangames holy crap

The Epic Tale of Gunhat the Just.

To the team behind this game, thank you. The first demo was released 7 years ago. So much work to put into, so many ideas scrapped, and so many hours dedicated to a passion project. At any point during those 7 years you could’ve quit, much like most other hundreds of fangames that never saw the light of day. But you didn’t quit. This game being released is a testament to the strength an online community can have. You pushed onwards through sheer passion, dedication and of course, determination. Thank you.

i do love the fact that the reoccuring hotland vent gag is even in this,which makes this 4105% more accurate. there is no deeper reasoning to the specific number.(if you don't know the hotland vent gag, every official undertale trailer IN EXISTENCE features a scene with the vent puzzle from hotland, as well as humorous text. the fact it's here makes this whole thing way better)

I love the way you draw Clover so much.

We finally made it to the release! What a journey it's been, congratulations to everyone and their hard work on this game! I can't wait to play it!

Words cannot describe the gratitude the fandom as a whole have for you guys at TeamYellow due to sticking and finishing a project, which is sonething most people were unable to, we salute you.

I love how all clover does all of the spare acts for thw monsters in the last little bit, it’s a really nice touch

SUBJECT: Yellow Soul STATUS: Hired AWAITING ASSIGNMENT

This.... Looks..... AMAZING!!!

Just finished the game for true pacific, if you and your team reads this then let me just say….what an incredible game you have made, these 7 long years have been worth the wait indeed. The way you guys made me feel the same emotions for these characters just like undertale did when I played that the first time is insane. Honestly me and ALOT of people think this should be canon, Toby himself should play this game it’s that good. Thank you guys so much for putting in so much hard work into this, you guys deserve a HUGE break. If this is the end for your team it makes sense after how long this took, but if not and you guys will make more stuff (even if not UT related) I promise I’ll be waiting for what y’all make next. Stay safe and once again, thank you.

I Just finished the game. Pacifist route. Aside of two noisy bosses, most know who they are... I enjoyed the tar out of this game. It Certainly lives up to the legacy it is setting to share with. I really enjoyed every single character I encountered. Honestly, despite their boss-short-comings. I cannot really think of a single main cast character I really didnt like. The music is top tier. Certainly what I came to expect from an Undertale based game. I adored the art style as well. But oh GOSH, the music was just killer all around. Especially after finding out the tracks are in the game folder in ogg format. The final boss of pacifist was just incredibly touching and enjoyable. The visuals, background and the music. What a culmination, that boss I poured all I learned into. I was struggling at first, but I forgot about a single move taught to me early on. I was then able to boldly and confidently trudge along helping out. The end did catch me seriously off guard. I was almost in tears a few times from the final fight, but I was then driven over the edge realizing what was happening thereafter. The music, the story, the characters, everything just fit and ended this fun and emotional trip so well. I honestly hope this may not be the end of this endeavor, but If moving on to a different game is what you all do. I salute what you did here, and cant thank you enough for the work and effort put forth... Will I go back and do the opposite route. I dont think so. I have grown too attached to these well formed characters to want to hurt them. -.- Despite the somewhat happy ending, I think there was much more hurt unintentionally placed on them than I would have personally wanted...

About 3 hours in... THIS GAME IS AMAZING!!

Congrats on the release! This fandom is amazing and you guys worked so hard to keep it alive

Мы дождались господа! Благорим создателей за то что они проделали этот труд ради нас! Спасибо вам!

undertale but you have a gun. and I love it

Clover: gosh that was a clo-*Apple falls on him* OOF

This release made my son's day. The trailer looks great! Thanks for all your hard work!

its so good, that gamejolt couldnt handle it.

1 million views in 10 days, truly the greatest fan made undertale project ever with the amount of effort put into this!

This game got me to cry. Congrats. Thank you to everyone involved in making this masterpiece.

Holy crap, I completely forgot that Undertale Yellow existed! I remember playing the demo 7 years ago when I was a sophomore in high school. Didn't realize that development was going on all this time!

The animation is such a fitting homage to Temmies Artstyle, awesome!

I need more of this art style

*Toby has been real quiet ever since this dropped*

Just played the whole thing, not surprising, but... TEM OUTTA TEM!!! PERFECT GAME!!! GIVE YOURSELF A PAT ON THE BACK AS YOU BASK IN YOUR NEW GLORRY!!! The humor was spot on, the music was worthy of the original, the graphics were _better_ than Undertale like a bonafied official sequel, it crafted a good story that had me hooked, characters that I'll remember, great battles, all around a HELL of an experience that kept me entertained for 12 hours with two 20-30 minute breaks for food! Be proud of yourself, because I am proud of _you!_
