Deltarune was created by Toby Fox and first released in 2018, following the success of Undertale from 2015. Presented as a parallel story with familiar faces in new roles, the game built a large fan community that shares clips, fan art and sounds across social platforms. The start sound became a shorthand among players for beginning something new, spawning edits and remixes that reuse its opening chime outside the game. Its continued use reflects how distinctive UI sounds from indie RPGs can become lasting identifiers for a whole fandom.
