We've released v0.0.247 for DELTARUNE Chapter 5 on Steam/PlayStation. This fixes a number of minor issues and bugs across the game. We plan to continue with a couple more patches.

A character in the game called "Shi" dislikes "Kikky". That is because "Shi" doesn't like vermin. (Maybe thinks Kikky is a bacterium) Also, for in-game setting purposes, "Kikky" could be thought of as just the cats from the Mike minigames (the Mikes must take care of them when not in use) (?)

I bought her the same cheap toy like 8 times and every time she instantly loses it and then starts yelling because she doesn't know where it is. Makes me wonder if she would have been happier if she never knew that Toy existed in the first place...

Kikky is my cat and I put an accurate simulator of her into my game if you can find it

Deltarune Chapter 5 came out IDK if you saw

IN THAT CASE PERHAPS WE NEED NO PREFACE.

WILL WE BE MEETING EACH OTHER LIKE THIS MORE OFTEN?

THE RESONANCE HAS QUICKENED.

DELTARUNE Chapter 5 releases in a little less than 12 hours! We've sent one last newsletter to remind people of the release! toby.fangamer.com/newsletters/...

From Toby: When I played this on the piano, my mom said "you know, usually songs do more than just repeat..." Sorry Mom. Anyway, the version in-game sounds very different. Don't be surprised.

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.

1 week until DELTARUNE Chapter 5! Are you ready!? (jumping around and spinning in place, jumping on your head, jumping on the bed, jumping around)

Chapter 5 has a lot of dialogue that you’ve probably never seen before!

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...

Monkeround Demo 1.3 has been released, coming in as the *definitive version* of the demo! Available now on Steam and itch.io! store.steampowered.com/app/3382860/... landimizer.itch.io/monkeround #gamedev

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.

The actual testing period will last for an indefinite amount of time. After that, the game needs to get approved on consoles and we need to do various other things to prepare for release. That'll be all from me on this subject for a while...

The professional testers are familiarizing themselves with the game now. They begin formally testing on April 1st. Japanese translation quality assurance is projected to be completed in April. Outside of addressing bugs and translation, most of the development team has moved on from Chapter 5.

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...

Now dat I got Verified who wants to buy my account

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/...

I finished annotating (most of) the translation with 8-4's assistance. I skipped a couple unfinished parts, but it's enough for the translator to properly start work on Monday! Yay!

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.

My friend said this affectionately as a joke and perhaps it doesn't have a deep meaning. They liked the game.

I showed another friend. Their testimonial was "What's the opposite of 'I miss 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"
