For one, the website was updated with some unused dialogue that was supposed to accompany an Undertale-themed alarm clock. It's pretty funny stuff that actually reveals a bit of extra lore for the megafan, so it's worth checking out if you want.
For two, Toby Fox actually used the occasion to tell us that Deltarune is not only still in production, but the next episode is almost done. Which might be one of the best slabs of news I've heard all year.
"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."
And finally, Fangamer, Toby, and the folks at 8-4 put on a live Undertale concert, which was streamed for the whole world to see. And while it's over by now, you can still watch the whole thing on Youtube, which I highly recommend.
All in all, it was a wholesome reminder of one of the most wholesome and uplifting video games ever made. God bless.
