dont know if its over but ı would say passcode 3
Somebody help, I cant date sans
Passcode two is the best choice! (Aren't I just the smartest?) >:p
Also, wonderful, wonderful game. Just finished WD and Pap's route, and working through Sans next!
I've finished Sans and Flowey's routes! They were beautiful. Honestly, I don't care much for Flowey, or for Asriel, but this helped him grow on me. Lovely writing- I'm super pumped to check out the rest of your games!
does anyone know the passcode for the book?
I just finished the dating Sans route, and oh my god, it's so well written and adorable! It made me feel so many feelings, this is awesome, keep up the good work!
how do I date sans? I cant figure it out :(
I want to be a wingperson but I can't
i feel kinda dumb asking this but how do you get past the part where you first enter the hot lands go to the laboratory and then gaster kills you and you hear a humming
Not sure if you have already saw the walkthrough already but to answer that ⬇️
Never let go of your notes 😅
And that part where it says "You have no choice" whatever, just wait for a couple more seconds 👍
thank you
DARKPETAL16. MAKE BONUS CONTENT WITH GASTER, AND MY LIFE IS YOURS.
All my old saves (༎ຶ ෴ ༎ຶ). I didn't save to disk ಥ_ಥ
Grinding time again (。•̀ᴗ-)✧
how did you make me like the love at first sight trope???
10/10 game, favorite route is the Lt. Blue route
OMGGGG I FINALLY FOUND THE SECRET <3
Was it the passcode to the book in the Librarby? What was it?
yup, can't tell you but I'll give you a hint, it's on another completed game (;
do you know which game?
I was looking forward to sans but ended up with papyrus instead. Never thought of him until mc talk with cinna about him and I be like.. huh??? Tbh the ending is really beautiful I cried a bit but it's all happy tears
I've always choose kindness because I love the feeling of being kind
It's indeed really good to playthrough
not quite sure how this works, and i think more than three people have gotten to this point before me, but the [redacted] soul is interesting. also +Wingdings 100% hes silly. also im too lazy to go to the other page but slumbertale sans is my close second favorite
update got my legs chopped off
i have bravery soul trait, trying to pull papyrus with me, but when i attempt to do the you look around to spot the voice it just shows <3 BRAVERY TRAIT instead.......... help?
personality guide????? anybody hello help im lost?????????????
Click on romance walkthrough
Sans- attracted to any soul as long as your bright (so choose all happy options)
Papyrus- multiple souls (the 2 I know for sure are determination and bravery)
Gaster- ONLY wise
Flowey- same with sans, any soul and you can date him
yes i know but there isn't "You look around and try to spot the source" action there's only the words BRAVERY TRAIT and i need personality choice guide blud!!!!!!!!!!
There isn't? I just tried it and there was that option
(I chose the Bravery trait)
because you stayed cheerful
i don't wanna be cheerful i need to be living pessimism in every IF!!!!!
i want to be pessimistic but i am "confident" for some reason when i choose anything except for cheerful choices
Pretty sure that IS for papyrus! That's his first interaction for you to date him.
Again amazing game. (Sorry for all the comments) I feel like it would be cool if there were side stories here like in Underfell
Of course you don't have to :D!
Edit: didn't do Sans's route so I didn't know there was already extra scenes for him
There's one thing similar between the Underfell and this one and it's that gaster is low-key a yandere (more so in this one lol)
Don't get me wrong I love this, but how (and why) is Underswap so much darker than Underfell 😭
I do like how it is darker since it would be assumed that Underswap would be much brighter (ig?). It's a neat twist :)
For some reason I can't romance Flowey? I followed the romance walkthrough exactly but I can't choose him when talking to Aaron :(
Er. I tore up the notes and got the option now but both walkthroughs explicitly say not to do that so I guess I'll see how I go.
EDIT: Turns out I accidentally activated the Papyrus flags, I guess.
EDIT 2: NOW I'm stuck at "You go down the stone steps." Itch won't let me put an image here but the box is tiny and all I can see is the box, those words, and the back arrow.
EDIT 3: I restarted the game from the beginning trying to limit how much I loaded saves or pressed the back button and didn't get stuck this time. I got stuck at the "grim reaper" monster instead, the exact same way as I did at the steps, and couldn't follow the walkthrough for that part, so hopefully that's not...too important? I saved around that spot so it should be fine to try again later. I should add, I got this same problem in the Horrortale and Slumbertale IFs. But not once did I get it in the one for Underfell, and I haven't tried Mafiafell yet. Also, I'm using Firefox, and I tried switching to Chrome for a second but the problem still happened - so it's not likely to be a browser issue.
I am so love in with this game.
I nearly cried at the end 😭 Why can't I have a happy life with a cute boyfriend too 😔
Passcode 1 hehe :)
*claps woops and cheers* ANOTHER WONDERFUL GAME!!! WONDERFUL STUPENDOUS LOVELY!!!!!!!!! and for those who need it i found(?) code so i'll drop it down.. im lazy
xY07BB13Zf16
I might be late but omg passcode 1 seems amazing--
i need more games like these
Anyone know what the passcode in the book at the librarby is ? I'm struggling
passcode 2 :)
passcode 3? hehe
It is just me? but
When i play Windings route i get the friendship route, even if I technically had intimate conversations.
Maybe I missed something? But I followed the walktrough or its the correct one?
Someone help pls
oh gosh, this made me cry. i love it so much!! <3 papy
I love Sans and Papyrus but there is something about Wingding that just gets to me. I love how possessive and affectionate he is. I wanna keep him.
This game warmed my heart. I loved the little notes they wrote to each other, and Wingding's messages in his route made me melt.
This was amazing. <3
... wow.
what a journey!
Underswap never had been my favorite au, I often would just go past it, but your IFs are my actual favorite passtime to read, so I gave it a try.
And boy I'm so glad I did! I usually go W.D route first, always, but this time I decided to give Papyrus one a shoot, just to be graced with the wingdings message all along the way in a smooth reminder I'd have to replay for my favorite skely boy.
Paps route is super fun, super chill, I crave more of this cozy feelings in any future extra/bonus scenes you may add!
But W.D route? Woah. Just woah. You got me feral here, my sweet protective crazy scientist, how much I adore how you write him, underfell him is amazing, mafiafell my favorite, but this one? Such a sweet surprise, all his scenes got me giggling and smiling like a fool, thank you for this, his notes with paps and sans are also really, really, wholesome. (Also pass 1 sounds fun!)
Thank you for this game! ♡
ok wtf bro this IS AMAAAAZZZING why WHY am i only finding it now. good gosh this is bloody good man
honestly both passcode 1 and 2 are interesting, hope i see either one of those next time :]
honestly they all sound interesting but im hoping for code 1 :)
extreme excitement when thinking on romancing the hell out of Paps. just something about puns is so attractive for some reason honestly. I admit my sense of direction is awful that I was running in circles in the two areas that had the character going in different directions. but it only made me more determined to keep pushing forward.
there was a thrill to searching for the notes while on the side hardcore romancing Paps [and later Sans when playing a second time through]. I restarted quite a few times due to missing items, and questioning where one would earn a pretty coin to buy items [which when did learn it was truly satisfying].
I also enjoyed the random bits with Gaster popping up, and just had a dark lil thrill going against what was asked [and flipping the screen when my desire to go against the order was useless] I got caught at the lab as I did not know about the patience of waiting a bit longer.
utterly caught off from Gaster's voice or well his humming. truly alluring with the voice actor that I ended up a second time with the ending before going to the walkthrough to find the answer.
from there I enjoyed the rest of the game and romanced both the skeelton brothers [excluding Gaster, as Siren Call Gaster got in my head seeing him as a guardian figure rip] also the surprise in the lab was such an interesting bit and just truly a good shock for what is discovered.
once completed I enjoyed reading the lil drabbles, a tasty and lovely bonus
Passcode 1 sounds very interesting :))
you this is so cool. And THERES MORE games like this?! what a treat(≧∇≦)
