Undertale Demo



The Undertale Demo was released on May 23, 2013 and can be downloaded off the official website.

Description
The Undertale Demo is extremely brief, buggy, and less detailed compared to the final game, beginning when the protagonist first fall down the hole into the Ruins and ending when Flowey judges you right after fighting Toriel.

Toby Fox has stated that the demo has a much higher encounter rate in the first area compared to the final game, most of the rooms only have one encounter, and you can flee from these encounters.

Endings
If you have killed Toriel and then tried to "fix" your mistake, Flowey knows. The pre-battle monologue with Toriel also changes to her saying that you look like you've seen a ghost.

Flowey's dialogue varies based off of what route you've walked.


 * Pacifist Route: Flowey will say what he says if you manage to spare everyone in the full game, then two guest appearances will occur on the credits screen, if and only if it was a perfect run.
 * Neutral Route: Flowey will name off the monsters that you've killed or call you repulsive and mentions that the protagonist's power to SAVE completely overrides his.
 * Genocide Route: Flowey will leave you off with some "interesting comments".

Manual
The Undertale Demo comes with a manual. If you view the manual that comes with the demo, you can learn about the mechanics of the game and some of the characters' personalities, along with their names.

The contents of the instruction manual may vary based on what path you took. The last page will be titled "A NOTE FROM YOUR FRIEND" and say "Don't get too cocky."

For example, if you decide to take the genocide route, all pages except the last and the first will change to the menu with the words "That was fun. Lets finish the job." written in red. The first page will be the default page (?) and the last will be a faceless Flowey. However, if you view the last page immediately after killing Toriel, you will see a different image, titled "A NOTE FROM YOUR FRIEND". It will say "You didn't even try to spare her. You murderer."

Trivia

 * The demo of the game is titled "UnderTale" rather than "UNDERTALE".
 * The manual was removed from the final version of the game for being too complex to work with.
 * This is the only known version of Undertale with an official Korean translation.
 * You are allowed to use any name. Even names that are forbidden in the final version of the game.
 * In the final game, if you kill Toriel and then go to sleep, there are two messages that you can get both using the name "Chara." In the demo, only one of the two appears and uses the name you choose at the start of the game.
