About
Fight (or spare) alongside new characters in UNDERTALE's parallel story, DELTARUNE...!
A massive soundtrack and story written by Toby Fox!
Meet new and endearing main characters, as well as familiar faces like Toriel, Sans, as more. Huh? Papyrus? No, he's busy. Sorry
Smooth and expressive pixel-animation by Temmie. She also has a new hat (in-game)
A linear, chapter-based system that you can pick up from anywhere.
Creative bullet-dodging based battles inspired by games like Touhou and Chrono Trigger.
Jevilishly difficult hidden bosses.
And...
...
... only 1 ending...?
Further chapters... you must buy.
Is Chapter 5 the last chapter?
Nope! The story is still continuing, and more Chapters will be added for free over time.

WHEN IS MY EGG. WHEN IS MY GREEN PIRATE GASTER. WHEN IS THE HOME TOWN BUTCHER.
So, I played this game pirated, but enjoyed it so much I bought it. Now here, in the year of our Lord 2026, I face a dilemma. Homosexuality in my video games... Why no Kris and Noelle, or Kris and Susie, or Kris and birdly ... and kris and ralsei... why no berdly king and kris queen or vice versa... why no date cat girl... why onion getting eaten and stuff... why the 2 parts in chapter 5 got me confused asf on what noelle actually wants. Why kris no slash friends when ruining date, but slashes them after they fight the knight... where in the world is San Frandiscoooo... what is jerona? why is there a purple man in a tu tu dating a suicidal cowboy.. why cat face do half my health.. why there a kid throwing knives at me... why does the same kid remind me of kris... why is your dad is my best friend... rudy is cool dude So many questions and more left needing to be answered
