Deltarune is an episodic role-playing game created by Toby Fox, first released with its opening chapter in 2018 as a follow-up in spirit to Undertale. Its music and sound design blend retro chiptune textures with modern piano and orchestral writing, which helped its short cues become highly shareable online. Fans cut individual effects and musical stingers from gameplay, streams and edits, turning them into soundboard clips for reactions and jokes. The brevity of this clip makes it especially reusable in meme videos and gaming communities.
