Deltarune is Toby Fox’s RPG about Kris, a human teenager who gets pulled into a strange parallel world called the Dark World and ends up adventuring with Susie and Ralsei. At its core, it’s a story about friendship, identity, choices, and how people act when they’re given the chance to play a different role in life.

What it’s about

  • Kris lives in a town full of monster characters, then stumbles into a fantasy realm where they’re treated like a destined hero.
  • The game mixes turn-based RPG battles with bullet-dodging and a strong focus on sparing enemies instead of just fighting them.
  • Its story is still unfolding, so part of the appeal is the mystery around what the Dark World really is and what Kris is doing there.

Tone and themes

  • It starts light and funny, but it often turns eerie, emotional, or surreal.
  • A big theme is how “playing” a role can change who someone becomes, whether that’s through costumes, friendships, or the choices the player makes.
  • It also plays with the idea that the player may not fully control the story, which creates a lot of speculation and discussion.

Simple version

If Undertale is about how games work, Deltarune is more about playing a part —in a game, in a friendship, and in life. It’s part adventure, part character drama, and part mystery.
