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.

2026年7月時点のレビューでチャプター1から随分と年月が経って未だに完結していないが、十分値段分の価値があると感じる。 Undertaleもかなり好きだが、完結していない本作の方が好きなくらい面白い
