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.

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.
Hi , I’ve built a SaaS product that helps users quickly set up their own personal community. It’s currently free to use — would you be interested in trying it out?
game is very cool but a bit difficult for me
Hey, I just defeated Flowy, and I'm given the choice of sparing or killing him. I'm not sure what I should do. Does this come back for me later if I spare him?
I'm kinda just going to wait for a response before making a choice, so I hope I get a response soon lol.
kill him and he will go knew you had it in you well at least in normal undertail
Please first and foremost take care of yourselves. After that, thanks for making this game and for the clear effort you put into this.
I love this game's style and variety. It works great for me on PC, my phone still has the earliest Android version to, and I still play it when I travel.
I had just checked my notifications after a while, or the feed for itch.io. I had gotten caught up in a lot of other things, but this game is still clear from when I first played it, which was I don't know how long ago.
I am happy to see it still going and getting the help and support it deserves. It has come a long way. It makes me really happy.
Again great work, and thanks for this game, vyletbunni. Be safe okay.
P.S. What happened to the Android version? I still have the version from when it released but I must have missed the news about it.
He wrotten the holy biblie for this game, absolutely cinema (sorry i dont speak english
Hoooo new version, whats new?
i really wanna play this game i just wish there was a mac download option..
if you have a instel based mac get a windows 7 install on it using boot camp then upgrade to 10 or if you have apple silicon you can use paralells or use oracle virtual box then use windows 11 for arm because it is easier to get windows 11 arm
crying in no arrow keys
No way bro Delta dunarii on itch. Io 🙏
