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.

Then when's Chapter 6?
We are aiming for a 2027 release! Meanwhile, we will be periodically releasing information on the development progress of the game.

He tenido que jugarlo para darme cuenta de cuánto echaba de menos el humor y el corazoncito que tenía Undertale y que también tiene este juego.
lgbtq. noelle and susie are FRICKING DATING. i like ralsei tho :) anyway i couldnt play much of ch5 bcs at the start i found that noelle and susie are dating. honest and i mean HONEST shame because the story, characters, gameplay, and map is so good. once again, i hate you toby.
可以可以
This game made me laugh, but also cry and shrivel against the corner of my room. It is really fun and full of secrets. with many gameplay changes and out-of-the-box thinking. Just play it, I assure you will buy it once you made the free chapters and crave for more. 10/10 Made my life better.
