DELTATRAVELER
A downloadable game for Windows and Linux
Kris and Susie (DELTARUNE) suddenly wake up on a flower bed in the world of UNDERTALE. They, along with Noelle, must travel between different worlds to make their way back home.
This is an UNDERTALE fangame that combines elements of DELTARUNE to create an interesting experience, both in gameplay and in story.
Feel free to send any bug reports to deltatraveler@vyletbunni.com

i would love a mac version of this game i hate that i cant play it :(
have you tried wine
dont see how alcohol would fix this issue but if it helps take your mind off of it...
I'm a mac user and I played this game 2 years ago and returning to it today! Use crossover :) It has a free trial. I paid for yearly like two years ago and it hasn't charged me since that year which is weird but whatever, it still very much works!
Could there (eventually) be an option to change the Kris sprites to the old ones? Not sure how many people want the same, but would be nice optional feature.
Personally, loved 'em more; but I can see the appeal in the new ones. So switching in-game would be nice.
Otherwise, great f-ing work! Keep at it!
hoping for the section 4 and 5 merciless route to be as fire as the others
HIIII!! I played this game before, before the update. How can i play the update with my old save file? I don´t want to do everything again :")
came 2 years later to say once again that this game is shit
I rather wish that I had the gall and time to learn how to fix and completely take over this game.
Idea and gameplay are good, but the dev is a massive pussy.
And you are also acting like that I am serious about me taking it over....still tho, massive pussy.
Bro, you're the only wimp here. You're the one getting offended over a fangame.
waaahhh wahhhh the developer who is making a game for free that nobody has to pay for, is doing something i dont like waaahhh wahh
Are you a freaking sociopath ?? No like genuenly what is your problem just say you dont like the game if it really was as bad as you are saying other people than you would be hating on the game why cant you just say its an opinion ? Also calling the dev a "Pussy" and talking in such a vulgar way instead of giving any reason for hating insulting a guy taking time out of his day to develop a game and make it free for everybody to enjoy and the only thing you find to say is that the dev is a pussy because he doesnt do what you want to do ?? thankfully you arent running the game it would be awfull its not because the game is not for you or that the dev doesnt have the same vision as you that you get to call his game shit and call him a pussy you are just immature please never comment again
Tf is your problem? This game is amazing.
Well, I much prefer to have a story that doesn't retcon itself in a patch because the dev made the literal murderer Sans into a blind pussy because he was actually awesome.
Oh, and how the game handles the Earthbound section I've grown to hate. Shows how much you aren't allowed to have fun killing. Much like how Underfell Sans was stripped of his "murder is fun" angle. Let me murder in a UTDR game for fun, damnit.
KRIS WHERE THE F*CK ARE WE
I want android version please 🥰😭
they released new au since underfell? ill go play it again if ye
I've been speedrunning section 1 for quite a while, and I love this fangame. It was actually my first!
If Error!Sans, please include a reference to Aftertale-oh wait, better then that. If he does appear then please include his biggest nightmare.
the game looks really cool ! but the controller support doesn't work for me (i'm on windows) and it gets me to struggle a lot in battle because i'm used to play with controller :'')
Hi there! Im a composer and i love the music, where can i find it ?
controller support doesn’t work on linux :c
WE, yes WE, need a macos port of ts 🥹✌️
Cake logic has a web port of it.
What a great fangame, I loved this all the way through.
What do i need for this to work???? I tried downloading it but it didnt work:
gamejolt
I wish I could install this on my school chrome book
ts so peak
No se por que a varios les disgusto tanto la seccion de underfell, no la vi mala me parecio realmente decente, la pelea con fell sans es muy buena, no es tan dificil pero si es bastante entretenida, tambien el encontrar a jerry, es una parte corta, claramente la de "oh, mother" fue mejor pero la de underfell no es para que dijeran que es total basura
To peak fangame section 1-2 to absolute garbage on the third like guinely who thought was cool to do those kinda fight with vanilla ennemy but hihihi they are red ? And don't get me started with the papyrus trap they are so bad the one you fall with the X and 0 literraly crash my game and is just annoying to do
oof talk about a complainer who doesn't understand how games work
I hope you and the team are feeling better after two months. The project is of little importance compared to the healing process.
i love how the windows x64 and x86 build are swapped
BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
I'm going to hope this is just your napstablook impression.
God damnit Kris when is section 4 coming
herobrine seed?
god dammit kris where the hell are we... the game
Wait, so is there never gonna be a section 4? I see a lot of comments stating that there wont be any more updates
After reading the news post I hope that deltatraveler is never rushed!
welp this was fun why it lasted thx for the experience i enjoyed this take ur time
No more updates from further on...
Hey hey, hopefully this'll get seen; the Ice cap encounter before Greater Dog has a typo in their initial flavor text!
How much longer is the game now?
what is that
ai generated is what it is
Damn, I'm glad I still have the mobile version downloaded. Sad it got discontinued for mobile; my laptop is absolute dogshit, so my tablet is the only place I can play the game on without lagging.
what are the minimum system requirements? my laptop is an apple IIc
Im back mfers
I'm just like the first person to find this
I want to disappoint you, but judging by the comments, you are not the first.
im not lying the commenst shoulda gone further ill post a screenshot
he didn't post a screenshot
here it is
i can´t believe its free!!!
thats very good say !
genuinely so so cool >U< and the amount of content for a FREE fangame?? super duper excited for whenever section 4 gets completed >w<
how do you make it full screen
use f4
four frogs
They're updating the Android version, meaning there won't just be the classic version, but also an Android version of the latest version of Deltatraveler.
