Hello everyone!
We’ve managed to release the demo somewhat in time for Undertale’s birthday. This is still a bit buggy in some parts, but we’ve added an auto-update feature, so usually we’ll have fixed a bug or two whenever you re-open the game. Feel free to report any bugs you may find, this is kind of a beta-ish demo. Have fun! <3
By the way, if you make a video on this game, please put #disbeliefgame in the description, so we can find ya!!!
DELTARUNE if it had good writing:
Some of Phase 4's attack I got done earlier... I was surprised that it was still dodgeable with Undertale's blue soul gravity, but I might make some adjustments to the beginning part just to make it slightly less tight...? It might not be necessary.
Welcome everybody, to the brand new official Undertale: Disbelief community on Game Jolt! We hope you'll come join and hang out!

Today marks the 9th anniversary of my Undertale fan animation "DISBELIEF" on YouTube!!!
As you know, we're currently working on Undertale: Disbelief, the playable fangame version. Expect an update post later today, along with a little community challenge!
I started writing a proper cutscene system. The one I had before was not very good... but this new one is making me so proud I could shed a single tear.
