GENERAL WALKTHROUGH - IF - Underswap by Darkpetal16
and the cod is in one of the games just look it is before dust
I'm so curious on what the keypad in the soul types page is!! I can't think of anything it could be.
hiii!! i loved this game sm bro, and im pretty sure ive played throuh every single one u posted (even the incomplete ones)!!!! but quick question, will there ever be a harem route in this one? i have the code for it, so was js wondering!
Wish i could've romanced Asgore lmao
You're so real for this
IMAGINE HAVING SUCH A GOATED GAME THAT PEOPLE ACTUALLY NEED A WALKTHROUGH HELPPP
Fav interactive fiction on this site next to ‘when twilight strikes’ 🔥
AGH YOU’RE SUCH A GOOD GAMEMAKER RAAAHHHHHH
I keep dying and retrying waterfall how do i help our boi w.d????
Slumbertale Sans
How do you find the code for the computer
When you can't figure out how to romance Papyrus-
I actually want to date the third skeleton though...
Adorables
absolute adorables
Amazing and super CUTE
What is the music in the Loox and Migosp fight, called? It's one of my favorite songs here. <3
AHHHH true sans end <3
I'm fucking stupid how the hell do i get past undyne I get dissected then just fuckin die and have to reload the save (its the same save when I died)
I'd love to know if you're planning to continue making these games, will you be making one for StoryShift? SS!Asriel and SS!Chara routes would be a blast to play. (Especially Chara.)
I always get lost in the fog, what is the right way to find everything? 😭😭
There's a guide in the development log if ya haven't noticed yet
North, East, Exit fog: pick up key, Leave, 3 South, West, Exit fog: meet the bunnies, Leave, 3 East: pick up note, and 2 North 👍
I figured out that the fog maze was a 4 by 4 grid, you start at the top far left second box down.
Sorry for the dumb question but how do you check your journal? I assumed it was the star button but it doesn't work and I can't find anything that does.. also great game thank you!
Press/click the bottom of the game and you will see a pencil and "CREDITS", press the pencil and there's your journal 👌
Thank you so much!
It’s made in Twine, it’s a pretty handy software for text-based games like this one.
I've made several things in Twine, though I never really add pictures (I'm not a fantastic coder).
can I just express how much I love asriel
dude. I LOOOOOVE the music!! legit dancin' everytime a different song starts playing. And AAUUUGHHHH Papyruuuuuss-- I am seriously kicking my feet giggling like a school girl, over this lanky-ahh man. WE LOVE YOU SO MUCH DARKPETAL!!!<333
how do you romance Papyrus?
You first have to have a certain soul trait, but I'd suggest just using the guide, it'll tell you exactly what you need to go on his route.
I FOUND THE UNDERSWAP ONE
I was just a out to reply to you about this game XD
haha XD
It's so touching... The atmosphere is very pleasant, including because of the music. Thanks to the author for creating such wonderful works!
(❤´艸｀❤)
i was so confused why i couldn't get on papyrus's route in snowdin even though i had humility, but i realized it was bc i had to say i loved puns when asgore made one in the beginning T_T
I keep dying to gaster, help!
There is a walkthrough if you need it <
Anyone know the code for the book?
its on another game
I heard it was in IF-Underfell, But I can't find it
I dont remember which game it was on ım sorryy :((
im pretty sure it’s a computer code on fell. on there it has numbers and letters, but you only use the numbers here.
maybe you found it by now but it is in underfell in the latter part of the game,
the labgood luck on your searches !
Where in the lab, though?
during the starting part where you first enter iirc
when you need to access the elevator and you get a codedont 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 also want to know
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?
