Reading the earliest chapter 5 ideas when I made it up in like 2016
Seth concept art... I guess the thing around the neck was originally a flower, but I'm not sure what it ended up as in the actual game
And one more thing... I also voiced "Chapter 5 Logo"!!! It was so exciting and fun to record my own voice saying "Deltaaaaruuuuuuuuuune!!!"✨✨✨
【DELTARUNE Chapter5】Now that a month has passed since the release, I think I can finally share this. I arranged the song "I guess I'm in love". Experiencing that moment in the game was truly beautiful, and it really touched my heart. Thank you so much.
【デルタルーン Chapter5】リリースからひと月経ちましたので改めまして… お祭りの後の『I guess I'm in love(恋かもしれない)』の編曲をさせていただきました。 とても印象的な場面に携わらさせていただけてうれしく、ゲームをプレイしたとき自分でも心がじんわりしました。 本当にありがとうございます。 そしてもうひとつ… 『Chapter 5 Logo(Chapter 5 ロゴ)』の声でも参加させていただいていました!! 「Deltaaaaruuuuuuuuuune!!!」と録音するのが楽しかったです✨✨✨
Kikky is my cat and I put an accurate simulator of her into my game if you can find it
From Toby: 10 years ago I made a song that sounded like this. It's called "The Sunset of 7 Suns." This is the hope for Chapter 5 from 10 years ago.
Last time I was at the store with my parents, we were looking at novelty socks and my mom picked these up and said quietly, "Undertale?"
These guys are called FLORADINN. You can think of them like the “Rudinn” of Chapter 5. Their favorite thing is FLOWERS. They usually don’t get what’s going on, but they are chill and don’t care. I like these guys.
Sorry to keep you waiting! DELTARUNE Chapter 5 will be released on June 24th at 11:00AM EDT. Here's the trailer if you missed it! www.youtube.com/watch?v=n5y2...

A message for my fans in Latin America. (plain text is in the image alt-text if you need it for translation.)
I'm so thankful for @tuyoki.bsky.social . She draws so much amazing arts all the time for my game. She draws almost everything. Even boring stuff like chairs. I don't want to draw a chair.
I was able to play this game years ago. I really liked it. I highly recommend it.

We'll receive the first draft of the Japanese translation of Chapter 5 next week! Meanwhile, we've been polishing the game and doing some preliminary internal bugtesting on PC. Heavy bugtesting across every console will happen when the Japanese translation is done.
A friend of mine was using a tool to analyze market research for his game. As a check he tested it on DELTARUNE. Seems like I have a lot of things to work on...

DELTARUNE WINTER Newsletter Time! We're sending it out now, but it takes a good while to process hundreds of thousands of emails. Fortunately there's a cheat code to look at it whenever you want. Ha ha ha ha. toby.fangamer.com/newsletters/...
Now that's Winter, I'm thinking about NEWSLETTER. But I haven't written anything for one yet... Right now, my energy is going towards preparing Chapter 5 for localization. The translation process begins next week. We have extracted all the English text and we are now annotating it.
www.youtube.com/watch?v=KAxW... New commercial from Fangamer! I wrote the spoken text, but I didn't end up seeing most of the visuals until the commercial was basically finished. Steve and Everdraed did an amazing job with them. (Also, it goes without saying, but commercials are non-canon.)
And now a word from Mr. "Ant" Tenna…

I had a friend play through an early unfinished version of Chapter 5! Their testimonial was "I am still thinking about it a lot and want to play it more and it's kawaii when toby is worried about if it's good enough"
