Deltarune is a role-playing game by Toby Fox, creator of Undertale, with its first chapter released in 2018 and later chapters following in an episodic format. Its sound design leans on crisp, retro-inspired effects that recall classic RPGs while feeling modern and expressive. The jump effect became a favourite among fans who ripped game sounds for edits, fan projects and soundboards, because it is instantly recognisable to players yet simple enough to reuse anywhere. It remains popular in gaming communities alongside other short effects used for comedic timing.
