Questions About The Game

Q: How does this game relate to UNDERTALE? Is it a sequel?

A: Please don't worry too much about that.
Essentially, this is not the world of UNDERTALE.
If you completed UNDERTALE, the ending and world are as you left it.
If everyone was happy there, the people in the UNDERTALE world will still be happy.
So, please don't worry about those characters, and that world. It will remain untouched.

To rephrase that, DELTARUNE's world is a different one.
With different characters, that have lived different lives.
A whole new story will happen...

I don't know what you call this kind of game.

It's just a game you can play after you complete UNDERTALE, if you want to.

That's all.

Q: So there's no connections between the two games?

A: It's a different world that might even have different rules.

That doesn't mean there will be no connections at all though.

Q: Any closing remarks?

A: Thanks for playing my game. I hope you liked it.

For the past 3 years I've been waking up in the middle of the night unable to go back to sleep because I've been thinking about the scenes that happen in the game.

Even though so many details are still hazy,

I really want to show you the things I've been thinking about.

That's really my only reason for making this game.

If I don't show you what I'm thinking, I'll lose my mind.



By the way, I was really worried at first about making this.

The expectations for my next work would be really high, so high that I knew that no matter what I did, I felt like people would be underwhelmed.

If you played "UNDERTALE," I don't think I can make anything that replicates the exact feelings you had then.

However, it's possible I can make something else.

It's sort of simple but maybe you'll like it.

See you in ?? years... OK?

Don't forget.

INTRODUCTION

Hi everyone.

If you're reading this, you must have been sticking around for about five years.*

I want to express my gratitude for everyone that has supported and encouraged me over this time.

Thank you.

I've said it many many times before, but I didn't expect the simple game I made to receive so much attention. Because of that, many interesting things have happened, and now I can even spend my time making another game.

It seems both of us received a lot of happiness from this occurrence.

If it's okay, I would like to keep striving to do things that make both of us happy.

Let me know what you think about that.

* Since the UNDERTALE demo released in 2013, the game has really existed for 7 years. It's already been more than 25% of my life...

DELTARUNE

I will make another.

I am making a game called "DELTARUNE." It is the second game in the UNDERTALE series.

The game will be released in many "Chapters," the first of which I released two years ago on Halloween. Since that time, I've been working hard to figure out the rest of the game.

However, it's a game that's much harder to make than UNDERTALE.

• Graphics are more complicated and several times more involved

• Systems are more complicated

• Exposes the weak points of my creative and artistic ability

• Plot is much harder to tie together (more characters, more important locations)

• Significantly more content than UT in 1 playthrough (especially cutscenes)

• I have only made one game ever

Unlike UNDERTALE, this is the type of game that would normally have many designers working on each aspect of the game.

A story writer, a composer, an audio director, a map designer, a battle designer, a minigame designer, and an overall director. Instead, all of those roles end up handled by me.

The good news is that a few months ago, I completed a significant milestone regarding the game's design. I completed readable outlines for every chapter in the game, including first-pass dialogue for almost all the cutscenes, examples of the music, etc.

Although certain details are still hazy, the flow of the game and all major events and battles that take place are now clear.

In summary, I largely spent the past two years writing, composing, designing, and drawing. However, that's not the whole story.

We had actually attempted to develop the game since the time too. Development started around March 2019 and a 99% work was spent on investigating engines alternate to GameMaker, which I used for Chapter 1.

Without getting into the details, I decided a few months ago to go back to GameMaker after all. It still felt like the best fit for the project. So using Chapter 1 as a base, we've started creating Chapter 2 since May 2020.

A lot of progress has been made since that time. I believe we can complete this chapter, content-wise, before the end of the year (not accounting for translation, bugtesting, and porting).

I feel very confident. And the strange thing is, even though we ended up using the original engine, I don't regret the lost time, either. Not only was I still busy designing the game, but during that long period, I was able to think of many ideas that make the game's story and characters better.

I'm glad that I'm making the DELTARUNE that I have now and that we are making healthy progress.

NEXT CHAPTERS

Originally I had planned to release chapters only when all them are finished, but honestly, it's hard both for creators and fans to go a long time without a release. So, I changed my mind. I think most people will be happy about this.

My next goal is to complete Chapters 3, 4 and 5 for next time. Then, at that time I will ask for people to buy the game, at the price of the first 5 chapters (including 1 and 2). I don't know the price yet, but it's definitely going to cost more than UNDERTALE.

So, next time you want to ask "when's chapter 3", you can ask "when can I buy Chapter 3/4/5? I'll give you a lot of money".

... I won't know the answer until it's done, though.

以上为所有现存的、官方的解释。

另外，Toby曾经在推特上发文称，UT的众筹资金过多了，他表示会制作一个比UT更加黑暗的游戏。

原文有图片、网页保存，但无直接证据表明这个黑暗游戏可能是DR，我这里仅提出此内容，免得有人把这条也乱说。
