Δ Deltafall

Something went wrong.

They weren’t supposed to be here.

Kris and Susie were heading toward a new Dark Fountain. But this time… it didn't open into a Dark World. It broke something. Tore it. A crack formed in the code of reality—and through it, they fell.

Into a world that isn’t theirs.

They land in the Underground, but it’s not the same. It remembers Frisk. It remembers a story that’s already over.
Except Frisk is gone. No one speaks of them. It’s like the timeline rejected its chosen vessel… and accepted the wrong ones instead.

Kris still holds a blade that’s just a pencil. Susie swings a sharpened school supply like it still carries weight.
Ralsei is here too—he shouldn't be. He’s a Darkener, and yet... he's alive. Real. Glitchless. At first.

But the seams are fraying.

Glitches flicker at the edges of the screen. Save files scream silently when touched. Dialogue rewrites itself. Something watches. Something is trying to understand who you are.

What broke this world? Why does it remember a child that no longer exists?
Will the cracks deepen… and let more in?

Or is this all just a dream your SOUL refused to wake up from?

🎮 Deltafall is a psychological horror fan experience inspired by Deltarune, Undertale (all by Toby Fox), and Deltatraveler (by VyletBunni). With glitchy aesthetics, story-driven mystery, and dark atmosphere, this isn't a game about saving anyone.

It’s about what happens when you force a story to keep going after it ended.
