DELTATRAVELER WEB PORT
A port of DELTATRAVELER to WebGL for you to play on Chromebooks. :)
Note: This Project is a mostly finished state. Any suggestions for mods will be ignored, as modding is not the main purpose of this port but rather the simple ability to play the game in a web browser. Please report any bugs in the comments below, and do NOT just say something along the lines of "GAME BROKEN! FIX IT PLS!" I need details about issues, and I will respond to you when I can.

There is a minor bug in the sans fight section where kris's face moves to the center of the screen of a second LO
This game is so PEEEEEAK
Its... not even starting..
Edit- It works now!
The game keeps crashing during the final froggit duo.
IT's OFF SCREEN
YAYAYAYYAY!
iz very kool
FINISH THE FUCKING GAME PLEASE ITS BEEN MONTHS
MY PROGRESS FIX IT
if you have recently cleared your cookies or used a cleaning app, then i am afraid your data is gone
ty ty ty soooo much
add fullscreen
Ok let's try adding that.
Edit: Oh no wait. That exists. Just press F4
I'm on chromebook so I don't know how
just know this is joy-con-compatible
It's compatible with PlayStation, Xbox, Nintendo, and Generic controllers. I've always thought of how cool Delta traveler on the Xbox would be.
it'd be sick on ps
Sadly impossible without modding
lol
I die ALOT of times on the end of section 3 so far it is GOOD I love this game and for some reason every time I start again it is glitchy for a bit. then it runs smoothly as I play. (im also on a chromebook that I won and got for free with a 500 gig plug in device so that could be why)
Thanks a lot - the offline download works! However, is it possible to optimize its performance in any way? It runs smoothly on my MacBook, but just barely manages 10 fps on my school Chromebook. I know it's just because school Chromebooks are absolute garbage, but still - is it possible for you to do anything on your end? Thanks!
Sadly, this is not possible without sacrificing play ability. The system I am using requires a computer with a decent amount of ram, 8 gigabytes at best. Most Chromebooks only come with 4 gigabytes of ram, and is not up-gradable (by default). So if you want to play Deltatraveler offline on a Chromebook, then this is not the silver bullet to your problem. It "Works" in the loosest definition of the word.
That's alright, at least I still have 3 more savefiles on my MacBook with this!
I mean... if you are doing this on a MacBook, why not just use the official MacBook download? This was made more for devices with a web browser but no official port of the game.
I am using the Mac build on top of this one, so now I have even more savefiles.
Ah, I see. Fair enough.
I don't wanna sound like a D1 complainer, but it still doesn't work. I launched the Offline Download locally on my Mac, and it was just black. I've included a screenshot of it with the console opened up. Also, could you somehow make the game canvas bigger when it launches?
Did I do something wrong this time too?
It is not that reliable of a system so don't expect it to work first try, you will need to refresh frequently. And about the scale issue? What would be preferable? And besides you can just press f4 on your keyboard to Fullscreen.
Edit: Do give it a moment to decompress it first and if that doesn't work, then refresh it.
2nd Edit: Sh*t nevermind. I'm just a dumbass. It should be fixed now.
Thanks!
Enjoy! ;)
launched for me idk what you mean
It doesn't launch or load correctly if you try to run it locally. Even running it with the itch app doesn't work. Its just a tiny black window. I've included images from trying to launch them locally from my school Chromebook and personal MacBook respectively. My school's blockers don't block HTML files normally, so I guess something's wrong with the file. However, other people seem to be having no problems. Am I doing something wrong?
OK yeah there are a lot of problems you have going here. First of all, you are trying to access it out of a zip file. Web browsers can't read Zip files without a third party interpreter to unzip the files. And second of all, that build was meant to be used on servers to be hosted by other unblocked game websites, not for offline usage. If you want to play Delta traveler offline, you should just go get an official download from the original Deltatraveler page. And for all my Chromebook users, I have not yet gotten an offline download developed quite yet, but I am working on it.
Oh, I see. I realized my mistake of opening it through a .ZIP file after I commented, but I tried it without it, and it still didn't work, so I decided there was no point editing my comment. Thanks for the info!
Good news. There is now a downloadable version of it to play offline on your chromebook.
how
Simple. A little something called Base64. Look it up.
also add where you can kill EVERYTHING
:)
Pretty sure that is just a thing in deltatraveler called the obliteration route.
it is called genocide route not "obliteration route"
Also add more games in here it's fun going through all of it
No. That's in UNDERTALE, not DELTATRAVELER. In this game, it is called the obliteration route.
its also in deltarune
it crashes at the very end
At the credits?
no after undyne chases you and you go in the grey door
Ah, whatever. If you got to that point, I count that save as completed.
finish it, and how to get all secrets?
any secret names besides gaster?
boi the crash scares me,im playing this at midnight (and please fix itttttttt)
Fixed one of them. Where else?
GOD DAMNIT NOW IT HAS BECOME A (to be continued) RAHHHHHHHHHHHHHH
my tile puzzle is impassable (NOT A SKILL ISSUE)
Might be a skill issue. Idk, didn't test it.
yes,it is a skill issue
Again, I don't know. I didn't test to see if it is possible to beat.
it is possible I did it
Ok thank you for clarifying that. Now we know. Also sorry for abandoning you guys for a while.
uh...
where's Deltatraveler?
I have the same question
Ummm... Well it is back now
so... why did Deltatraveler turn into a Garry's Mod? 😭🙏
NOOOOOOOOOO
MY PROGRESS!!!111!
Cake Logic, please add something to save the game before and after every update or something to skip parts of a game after an update.
Did your game also turn into a Garry's Mod? By the way, about the saves, he said that with each update the saves are reset, and there's nothing he can do about it.
oh
:(
at least he fix the Logic's mod problem
Yeah, and Deltatraveler is kind of a short game, so you can get your progress back quickly.
I may consider adding a level select.
As far as I know, the gary's mod thing was only in the trailer.
Pfft, that wasn't even close! That was just a side project I was working on, I accidentally uploaded to this page.
What? Me after realizing that I put the pizza in bed, and the baby in the oven: "GASP OF REALIZATION* OH NO!
Ok! The game is not gmod! It's deltatraveler. As for all your saves.... I'd have to see what I could do about that.
Hey, I finally finished the game, I did the pacifist route and managed to reach the end, thank you very much...
About bugs? I didn't see any that interfere with the gameplay or anything like that, just a few visual bugs in some enemies (Jerry, and Sans' attack when he raises his hand, and in the passage before facing Jerry there's a gift monster that also looks a bit buggy, and the credits scene after you see Undyne and enter the door crashes the game) but aside from that? The game is in perfect condition, now anyone who wants to play can play without any problems. Good job!
Finally!
We have definitive proof that the game is fully playable now!
no,i cant beat it
Skill Issue? Or is it crashing?
keep crashing and IT FREAKING DELETED MY PROGGRESS NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
its so perfect
Oh man I should dm Vylet and show them this. They're gonna be so flabbergasted. XD
Thank you for the update. Thanks to you, I managed to try the Obliteration route; however, I can't fight Jerry. On his second attack, the game just crashes out of nowhere, so I can't finish the route, and it turns Neutral. Also, when I access Sans' shop, the game crashes.
When you have time, it would be nice if you fixed it
Yes, I will attempt to fix these issues as soon as I can. I appreciate your feedback, it helps make this game more and more playable for everyone.
Yeah I fixed the problem, it turns out that the crash had something to do with his spin attack.
GENOCIDE ROUTE NOT OBLITERATION
Ngl, this man is js consistantly cranking out peak frfr
Snail Approved.
I approve of your approving of this game.
Snail Approved is Cake Logic Approved
Thank you for approving my approval.
I hope to see more peak from you in da future!
I love ultrakill
Haha run around shoot gun as thirsty GoPro
Haha red pistol go brrrrrrrr
ah, and also when I try to talk to Flowey in hard mode, the game just crashes
Hey, great job updating the game, Cake Logic. I finally managed to get past that part I mentioned before... However, when I reach Snowdin - Dogi checkpoint, and move forward a bit doing Papyrus' first puzzle, the game simply crashes. I know it's annoying... you just updated the game and there's already a glitch again... I would be grateful if you could fix it.
That's okay. I appreciate the feedback. You and everyone else here help me find and fix these issues for the best possible playing experience.
I'm not sure if this happened to other people, but in section 3, when we finished that game with Papyrus, the one who kept electrocuting you, then after that there is a bridge, and after this bridge, there seems to be an invisible wall that won't let me pass. I would be grateful if you could fix it (I am on the pacifist route).
Damn the mole boss is hard af
God damn it I hate Porky
I'm gonna make a new save just cause I don't think I can beat him myself on pacifist
porky is a EZ to beat boss now SANS' doppelganger (as sans tells you) IS HARD
darn It I downloaded the webgl, modded it for fullscreen, and now there's a impassible barriar in the room after the puzzle room. please fix!
toriel is HARD, also can someone tell me how to fullscreen, and if the download is optimized for Chromebooks?
Press f4. On chromebooks you need to enable the option "Treat top keys as function keys" In keyboard settings, and Press the Fullscreen button.
The download option is to allow other unblocked games website owners to host the game, but is not to be able to play deltatraveler offline. I may make a downloadable version that is also playable offline.
fun fact: if you name yourself frisk you become her in game plus there is different text if named frisk
First of all, that's "THEM" to you; they are non-binary. And Second of all, that's actually a pretty fun fact, but is already an option in the extras tab called "Hard Mode".
so the impassible wall he's talking about is in the cave right next to sans shop in part 2
maybe I just wont buy from him for now
ok so sans crashed my game haha
the obliteration route is so tedious
my saves didn't save
pls fix
This is an issue I simply cannot fix, every time I update the game to fix a bug or issue, all saves that anyone ever made on here get wiped. Otherwise it saves fine. Just be aware of that, this is more of a tech demo or one time play, rather than a permanent thing.
ok thanks
yoooo my first first commenter experience is nice
In section 2, there is an impenetrable barrier that makes it impossible to progress, I will fix this later today.
Edit: This is fixed (to my knowledge)
yipee
W hard mode reference
so hard mode crashes in the first puzzle room
I see what you mean. Yeah, there was a piece of code that crashed that cut scene in normal mode, I guess that's come back to haunt me.
Edit: Nvm, that was a different piece of code, It works fine, although if you compare my version to the real version, you'll notice that the lever isn't flipped. It makes the sound effect that it did, but it was the same as before.
I wish you luck on getting it fixed
the barrier is still there for me, this damn snake thing is taunting me so hard.
Where exactly?
Edit: This should be fixed.
section two in that cave area with the snake thing, I can't walk up to it without there being an invisible wall I can't pass.
What? I thought that was fixed. Lemme look into it.
Edit: Nope. This is in fact fixed in the latest patch.
PS: Remember, all saves have been wiped. Not my fault. Itch.io is to blame.
