Undertale is an awesome game made by Toby Fox. It is an RPG with bullet hell and avoidance elements and has a heavy focus on choices and their consequences.

“Okay how are we going to show the player the credits?”
*”Beat them up”*

[caracalkarting]

Undertale, the one game that made you fight credits, be scared of comic sans, and walk in circles for hours to find a kyogre.

“Now we have these two monsters with probably the hardest attack in the beginning”

Sans: I used to rule the world

[lemerbrix]

The fact that papyrus says “is sans pranking you across time and space? I hate it when he does that” makes it sound like a regular occurrence

[cheasyegg]

Why is papyrus so calm saying
"Is he pranking you throughout time and space?"
"I hate it when he does that"

[lobs]

Merg - no hit sans

Also Merg - dies to two doodles

[frenfrendy]

TobyFox: what would I choose for my persona in game?
"how about animal?"
"tobyfox"
"tobyFOX"
"yeah i'll get the dog!"

[spiritbaki]

- Spawns into existence
- Absorbs legendary artifact
- Takes a shit
- Leaves

[goldfinch]

merg: completes a genocide run without saving or dying, defeats sans without getting hit once

also merg: dies multiple times to an awkward apologizing aardvark-looking monster who uses a 3D tush wiggle attack

[Grey_World]

"Is Sans pranking you across space and time?" "Sometimes I'm a genius, all of the time" Papyrus.

[amirirrira]

Even when you talked away, you did it with a smile.
Frisk: -_-

[Strikery]

Toby really put a lot of effort in these. And they are just secrets. I’m impressed

[Merg]

A million views? I'm not crying. I just caught something in my eye.

IT'S TEARS.

[kalinaxbiss]

Even though it’s been like 4 years, people still watch this…it fills you with determination

[jilllandry]

Man don’t you just hate it when you have text to speech on and you accidentally program a whole game

[senkstudios]

The dog room and the ‘holes’ needing to be ‘patched’ is basically Toby saying: there are a lot of bugs and glitches I need to patch

[zys_monkey]

Fun fact: The dog residue can be used for temmie village, you can sell them then use it again. But you don’t use all of them, you keep one left, use that so you get more. That is basically how you get infinite gold.

[legoyoda]

Merg: and everyone is still here, undyne, papyrus
Captions: everyone is still here, fish sticks, waluigi

[movedchannel]

*Legends say that Merg has never changed his local computer time back*

[Bucketnetta]

It’s interesting how the first secret boss has a different hat each time
