The page has now closed once again. Previously, participants received their emails within 10-8 hours, so keep an eye out.

Just to preface: if anything happens tomorrow because of this, I might not post about it since I'm going to be busy with IRL stuff. So uh. If ya'll could wait on solving that code that would be nice.

Toby Fox is sending out emails entitled "Another Chance", linking to the secret "thankyou" page from the pre-Chapter 3 & 4 Sweepstakes update. deltarune.com/chapter4/tha... The page has two inputs, one for an email and one for a number. Seems like we have one more shot at this. #DELTARUNE

I got to make a santa hat and presents for tenna!! I assume they contain dog food

Spent the last few years working on Deltarune Chapter 3 and 4. Toby just posted development interviews and and more info on the development of the game. Take a read : ) toby.fangamer.com/interviews/c...

CHAPTER 5 STATUS: * Localization has begun. Professional testing will be done after its final stages. * Console testing will likely begin in January. * Chapter 5 still months away. * All rooms are done minus background polish. * Almost all scenes done. * Most battles are done but need polish. 🧵

A new optional scene from DELTARUNE Chapter 5 has been shared in the newsletter. It's a continuation of the last optional scene from the previous newsletter, that can only be done if you kept Tenna in Castle Town. Too big to upload on its own: email-files.fangamer.com/list_48/camp... #DELTARUNE

HELP WANTED! We've realized that we probably need a few new music artists, given the new ideas on the table for the rewrite and future. If you have music experience, especially with the UTDR style (as well as immitating other styles), feel free to submit an application! forms.gle/9HdbX5zEPakA...

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.)

New promotional video for DELTARUNE Fangamer merch, complete with more Tenna voice acting. #DELTARUNE
