I'm still here btw

I didn't know Undertale's epilogue was updated to be a bit longer recently! Though, this all seems familiar somehow...

“The underground is as big as you want it to be.”

I am overjoyed that I was able to help program Undertale's 10th anniversary stream edition alongside BeholdMaxine and colinator27! Thank you to Toby, Fangamer and our producer Robert Sephazon for the opportunity, and everyone else who helped along the way.

This was the first time I ever modded Undertale, so of course there were plenty of bugs as I figured things out. But the funniest one I got has to be this:

I really wanted Undertale's Hard Mode to be real, so I modified my save file to see what would happen if I fought Sans in Hard Mode, but this kinda sucks?? What was Toby thinking??

So yeah I made Mart Lightyear into a Desktoptale thing for the hell of it. Link in the replies below.

10 years ago, I played UNDERTALE for the first time, and it changed me forever for the better. During a tough time, gave me what I needed to begin my journey of self discovery. Happy 10th Anniversary!! #undertale #undertale10thanniversary #undertalefanart #undyne

Cool collab art I did with @teruniinamor.bsky.social (they also write a lot of cool stories and worldbuilding) #digitalart #anime #animeart #manga #mangaart #hatsunemiku #初音ミク #ミク #ボーカロイド #vocaloid #fanart #miku #illustration #fanartanime #teto #kasaneteto #oc

imagine being such a space cadet that you literally become space-themed

I guess, we need to say "I love Martlet!" 99 times... #Martlet #Doodle #UndertaleYellow

I JUST started the game and already it doesn't make any sense. Okay whatever.

Every time I think about the Egg Man or therapist from Deltarune, I only think about Dr. Eggman #DELTARUNE

Fine. You got me. So... Let the roaring begin!!! 🗣️ #Martlet #Doodle #UndertaleYellow

This is probably breaking SOME sort of rule

MP3D a game w/ @brysonmcbee.bsky.social out on itch for free

you order a physical copy of the Undertale soundtrack. you receive a much larger package than expected, inside of which is this baby. it opens its mouth, vocalizes the entirety of the soundtrack with unfaltering accuracy, then turns grey and disappears
