Undertale Yellow has got my feelings all mixed up now I've completed it. I so desperately want to rate it 4 stars because on the one hand it has a beautiful story (I went for pacifist) with strong, emotion filled characters - that had me genuinely in tears as the credits rolled, including a twist villain and new settings that definitely add to the worldbuilding and creative style of the original while being (very) faithful and creative with new concepts to differentiate itself, but on the other its creativity and gimmicks in combat have led to increasingly frustrating start overs.
I can't count the times this game made me want to slam my head into a wall because I wanted to continue with the story until I fumbled at the final boss and decided enough was enough and watched someone else beat the last 45 minutes of the game which I wouldn't have lasted even if I tried my hardest. The sheer amount of undodgeable attacks that do not care about being fair is uncountable and make me wish there was some extra polish because even regular encounters took a chunk of health out of me for that reason. One time I was close to a save point but lost to a regular enemy and had to restart and entire section all over again to reach it again.
Its a brilliant fan game, one of the best I've played, but my god do the fights need to chill. I probably won't be playing this again due to the frustrations of the battles but I might watch someone do the other routes.

Undertale Yellow is a very impressive fan-game! The sound, artwork, battles, and animation are all of similar quality to the original game. I also think that it struck a perfect balance of original content to reused content and characters from Undertale. That being said, I did feel like the story was a little aimless, and that the characters and humor are just not to the same degree of quality that Undertale set. The game does also take a while to get going, especially relative to its total length. It was still fun though, and I enjoyed the more difficult battle balancing.

By far my favourite Undertale fanwork. It's a really great balance of feeling like the source material while still having its own merits. I think the spritework is great and the characters are interesting, and I also like how all of them are connected even if loosely. Even though it uses its inspiration well, the game is at its best in its entirely original sections, The Wild East and The Steamworks. And being an undertale fangame, it's only natural that the soundtrack is great. You can definitely play the game even if you haven't played undertale, but understanding it all and beating the game will be much easier if you've already finished UT.

To be totally honest, I'm not the biggest fan of Undertale fan games. Simply due to the fact that they're over the top and lose the essence of the original game, but this one is the minor exception.

Undertale Yellow takes place before the 7th human (Frisk) fell into the underground but the 6th human (Clover) went to the underground to seek justice for the other fallen children that have disappeared.

I think this game did some things a better job than the original game. For instance, the assets and animations look really well made and give a lot of the environment and characters more life. Another thing they did better is the combat, it's a lot more thought out compared to the original game and it makes the game standout even more.

The cast of characters that you meet throughout your journey is pretty solid. Although definitely can't compete against the original cast but they can definitely stand out on their own. My personal favorite is North Star, which is more of a mixture of Papyrus and Sans personality together. They are also some side characters that you are able to meet as well and they're pretty memorable too.

The boss fights are really good and well made, even some of them I can consider better than the original. Although some of the bosses can be a little bullshit like Axis, but it's something that I can deal with. The difficulty scaling is pretty much one to one in the original. It's not too frustrating but also gives you little challenges throughout the entire game.

In terms of the endings, I think it is fine. I mainly did just the true pacifist route and I found it quite enjoyable. As for the other endings, I searched them up and are quite interesting.

Of course, it wouldn't be Undertale without talking about its soundtrack and this one definitely didn't disappoint. The soundtrack is pretty much a one-to-one comparison to the original and felt like this soundtrack could be a part of the original game.

Overall, this Undertale fangame did a really good job on recapturing the true magic and essence of Undertale. While it didn't really hit me as hard as the original, I still enjoyed my experience. I can absolutely recommend this to someone looking for more Undertale content that doesn't deviate to much from the original but still holds up as a standalone game

One of the best Undertale Fangames I've ever played! Love the characters, the gameplay, the music it's extremely good, especially because it's free. It is harder than Undertale, as the game expects you to have played it beforehand. The best section was definitely The Wild East, as this is where the games character writing really starts to shine with Starlo and the Feisty Five. Martlet also shines in every route, especially at the endings of both pacifist routes. My main gripes are the fact that in most boss fights, the ACT button does nothing but give flavor text. It makes the fights more of a waiting game, and also means that you don't do much in pacifist routes besides dodging and sparing in them. I also think Axis gets a better ending in neutral rather than pacifist, which left a little bitter taste in my mouth. I also wish Dalv either got more screentime or that his story wasn't so hidden away in easter eggs and FUN values. However, this is still a wonderful game, highly recommend! I've done the pacifist and neutral routes.

one of my most defining traits as a human being is my obsession with Undertale/Deltarune. i grew up loving EarthBound, had unregulated internet access WAY too young and would browse the starmen.net forums never knowing how to post (which was a good thing!), and the ways both Undertale and Deltarune have shaped my life can't be overstated. i don't know if there's any single artist whose work has impacted me like Toby Fox's. this is all to say that i went into Undertale Yellow excited, i had heard a lot of great things, but i felt a lil cautious to see if it really had that sauce.

and Undertale Yellow does not have the sauce.

i think one of the most interesting aspects of Toby's design is how tight the pacing in his games are, Chapter 2 of Deltarune in particular being absolutely perfect. the way it builds and escalates its bits, the constant forward yet fulfilling momentum, the delicate balance of exploration to scripted events, and the way (aside from the music robots) every character is introduced and explored are my favourite in any game. you never forget walking past a dumpster and having some weird little fucker pop out at you, you can't not laugh at Berdly and Queen - two of the funniest characters ever to be coded into Gamer's History.

it's impossible for me not to compare that to Undertale Yellow. Yellow's nearly decade-long time spent in the oven shows, with its first half feeling extremely sloppy. there's not much in terms of interesting characters, story hooks, level designs, or setpieces. it gets more exciting as it goes to more original places (ie not the ruins or Snowdin) but the pacing only improves towards the end. i really like the concepts at play with the Wild East but it's a SLOG. reminiscent of the wrestling part in Thousand Year Door where you just hang around doing a half a dozen lame fights/mini-games. it feels like you spend half of the game in that town. everyone talks too much. dialogue isn't as punchy as it should be, conversations and scripted sequences tend to drag on. there's not much humour in it either.

Undertale Yellow's characters and story never come together in a satisfying way. Asriel Dreemurr made me cry and feel funny when i was 13, but the way everything ties into him and leads up to that final confrontation in Undertale is one of the greatest emotional payoffs in any game. Clover is more of a character than Frisk, they're not a kid who simply wandered into the underground - they came here for Justice. to save the souls of those other kids who died! i think this isn't very good? it never feels like a goal of the game, it never has any relevance outside of the genocide route. Flowey's aware of it but he feels like an afterthought in this (unrelated but Asgore is esp OOC and it bothered me). the real central story of the game is Ceroba's backstory, it's just that she only starts to get built up in the game's last 40%. it's not as focused as it should be, much of its time is wasted on disparate characters and segments that never satisfyingly connect or resonate with the player.

one of the only areas that Yellow gets close to Undertale in is its combat. there's some fun bullet patterns, great boss gimmicks, and the neutral/pacifist routes are pretty reasonably balanced (maybe a little too easy?). i gotta commend the unique content in its main three routes, especially the clay parts of Flowey boss fight in neutral (the parts where it looks like it came from newgrounds suck tho). genocide route also slightly makes me feel better about Martlet.

Martlet is the stand-in for Papyrus, a wannabe royal guard captain stationed outside Snowdin who's never met a human before. her first section is rough. Sans/Papyrus are possibly the most beloved characters in any indie game, it's easy to see why when you look at how well-paced their section is. they're introduced in exciting ways, have an escalating set of setpieces/mini-games, and have great designs. i can't say any of that for Martlet - who only makes an impact after her section is over, mostly in the genocide route for me. all you see of her before her fight are a couple scenes where she sets up a lame puzzle that, unlike Papyrus', are not jokes. it never builds to anything, instead it wastes time introducing the fuckass cuphead guys and the "made before Spamton but is a scummy salesman so i'm gonna think of Spamton" guy. Martlet is just Papyrus if he was a wholesome, boring furry woman without autism.

i am going to talk about Dalv now.

i don't think every character Toby cracks out is a total winner. Cap'n Cakes aren't very thrilling, Chapter 1's King is mostly there to be an evil guy you need to fight, and Alphys' dialogue in hotland can go on a bit too long (tho i do love her). they're all, at worst, a little boring but either don't have much of a major role or are merely slightly flawed. Dalv, Undertale Yellow's first major original character, does not have any redeeming factors. i straight up hate him. his design? looks like an Adventure Time OC a 16 yr old boy would self-ship with Marceline. his dialogue? boring as hell. the way he's supposed to be Yellow's Toriel stand-in? absolutely shameful. the way he's just a lame human-looking vampire and doesn't fit in? the way his only relevance to the rest of the game is that he used to hang out with little girls? the way he just has lightning powers for some reason? i had seen almost every major character in the game online in fan art at some point prior to playing EXCEPT for Dalv and i see why. despite being the game's first important new character he never shows up again or has any relevance to the game so he doesn't fuckin matter, he sucks ass bad and i hate him.

Ceroba's sorta neat, though. she's easily the strongest character in the game, her story plays off a few aspects of lore from Undertale that are fun to see explored - her having a daughter who ended up as one of the Amalgamates in the True Lab is great drama. she's also the most Toriel-like on the surface, having lost her husband and child through tragedy. she's very un-Toriel like in how she actually still loves her late husband, the ways in which she still clings to his memory and (undeserved) dignity in death is relatable. if my wife died, i'd be gassing her up constantly. her section is the stand-out portion of Yellow as well, the Steamworks have the best momentum and variety of gimmicks. i gotta ask tho - why is she japanese? how does she know what japanese culture is? monsters have been stuck underground for a millennia, she and her dead husband should not know what a kotatsu is. the game is defo too happy to reiterate her backstory but she's the sole character who has an actual motivation to fight you, which is nice. still feels horribly unearned when her boss fight theme starts incorporating aspects of Hopes and Dreams though. like you are NOT him.

that unearned feeling captures how i feel about it as a fan follow-up to Undertale. i don't think Yellow has enough ideas of its own to stand apart from Undertale, it spends 3/4 of its major areas retreading Undertale and most of its characters feel like lesser copies of Undertale's. mechanically, it harms itself by adhering too close to its inspiration. its design isn't ambitious or experimental enough. there's not many moments where i found myself surprised, feeling like i haven't already played this before. it doesn't have enough of its own identity and i found a lot of its original aspects to be really weak. it's like the Blue Shift of Undertale.

i think Undertale Yellow is okay. it's a remarkably professional feeling game. it seems like teenagers online really like it, tho it has been nearly three years since Chapter 2 dropped and UT/DR fans are starving. it's well-made but it's not cohesive or compelling, it feels more thrown together than particularly inspired. makes me appreciate Deltarune as a follow-up even more than i already did. if you're an Undertale fan and you haven't played thru some of its inspirations (ESPECIALLY MOON!!!!!! PLAY IT!!!!!!) i'd recommend you just do that over this. Undertale's writing is maybe its most important aspect and Yellow's writing simply isn't very good, there's no glue holding it together.

plus i don't remember any of its music and there was a really bad fnaf at freddy reference

Was not really a fan of this game. It's really impressive 'asset-wise' if that makes sense, the graphics and music and whatnot are all good. The problem is that the story felt pretty bad and the battles were really obnoxious.

I played Neutral Route first (because I was spoiled from so many people calling it 'genius'...). What started as playing Neutral to see what Neutral had in store ended in me playing Neutral because I genuinely despised most of the normal enemies enough to rather be done with them ASAP rather than sit through lengthy uninteresting ACTs. Also, every area only had like... one to two enemies in the first half max which is absurd and grueling.

That being said, I haven't beaten any route other than Neutral for that very reason. That's how little I want to sit through the start of the game again, even less so without the ability to end a fight quickly. I heard the story's better on Pacifist and Genocide but like... man, I almost don't trust that with how disappointing Neutral was for me.

Even when you get past the battles though, there's the story. Lots of people praise it, I don't really see why. Maybe Pacifist is just that much better or something, I don't know, but the Neutral route's story felt like a whole lot of nothing, and there was occasionally times where I would actively point towards the screen and go "That's stupid!"

The one other point of praise I have for the game is that the third area with the town (that's the least spoilery way I can think to phrase that) was actually up-to-par in my opinion. Most of the game's jokes didn't feel funny and most of the interactions with characters felt forced and unnatural but this one area of the game shined to me as the one place with good humor and a good time.

I liked most of the main characters, I think they have a good characterization, I just think their participation in the story isn't the best, overall I think the direction and narrative fail them in some points. Secondary and extra characters? Undertale did better in this area.

I like the idea of ​​each route. Pacifist, the protagonist gains empathy for monsters and becomes a kinder, gentler person. In the genocidal route, they seeks to avenge the dead humans and becomes more aggressive and cold. On the neutral route, they ends up wanting to abandon is mission and reveals themself to be a very different figure from the protagonist of Undertale. It's not the kind of thing I see Toby Fox doing, especially considering how little meta-commentary there is in this game. I have no problem in that area, I'm not against franchises going for different ideas and concepts, as long as it at least doesn't offend the source material, which isn't the case with this game. It was just designed with the Undertale universe more in mind, whereas in the original Undertale the universe existed more as a pretext for its message. To end positive points, I think that all the routes suffer from indicating something interesting to happen and this ends up never happening or the execution was much more mediocre than expected.

Combat is a yes and a no for me. I like the higher difficulty, I always found the original Undertale very easy. It has more animations and sound effects, which help bring more life to combat. I like the way of attacking more, especially when you acquire another weapon, getting all six shots right is very satisfying. The problems start in the act and its little function throughout the game, it even helps to finish some battles faster, however, on the neutral and genocidal route the effect is minimal, killing enemies is faster and more practical. Bosses are even worst, act is just a flavor text almost all the time. The way defense and attack work in this game would have my preference in an orthodox RPG, but Undertale Yellow is a game designed so that it can be completed between level 1 and level 20, just increasing attack and defense makes the game extremely easy in neutral route if you follow at least a few levels, and the genocidal route despite having exclusive bosses that were designed with a high-level protagonist in mind, the rest remains as pathetic as the neutral route. Attacks are generally competent and even creative, but I'd be lying if I didn't think certain attacks needed more testing.

It has its flaws, but the emotional moments make the journey worth it.

This is the first fan game I ever finished, and I'm here kinda wishing it wasn't one.

Except for the 'Undertale' slapped at the title and of course happening in the same world, this felt for the most part pretty much its own thing, and could have very well stood on its own, kinda like Oddity is doing.

It's like how Mother 3 is loosely a sequel to Earthbound, only Yellow was way more bound to the trappings of being a prequel and attempting to conform to an already established canon. I don't intend this as a harsh criticism of the game, but I feel like it could've been so much more if it wasn't a fan game.

Granted, I only played the pacifist route, but I felt there were a few loose ends and stuff that could've been done better that just didn't sit well with me at the end and left me wanting. I was enthralled by it about halfway through, where the writing and jokes truly shines the most -- there were just SO many moments I laughed heartly, which isn't common for me in games. But it kinda lost me near the end, and I just don't feel like replaying all of it to see more of the game in different routes.
