In a recent discussion, game developer Toby Fox shared insights on concepts for Deltarune dating back nearly a decade, sparking renewed interest in his creative process. Fans are now contemplating how Fox's experiences shaped his work following the success of Undertale.

From Vision to Reality

Fox revealed that the finale for Deltarune came to him in a fever dream in 2011. At that point, he lacked the experience to realize this idea, leading him to create Undertale first. Little did he know, Undertale would exceed expectations, becoming a cult classic and potentially shaping the development of Deltarune.

Fans Weigh In on Foxโ€™s Journey

Fans are highly engaged with these revelations, expressing mixed feelings and theories:

  • Initial Concept vs. Execution: One fan suggested that Undertale served as an experiment, helping Fox refine his ideas for Deltarune. Another shared this sentiment, stating, "It's fascinating how Deltarune was conceived before Undertale, but he chose to create the latter first."

  • Misinterpretations: Some commenters find it reductive to view Undertale merely as a stepping stone for Deltarune. They remind others that Undertale was a fully-fledged project, noting, "It had a whole Kickstarter; it wasnโ€™t just a stepping stone, lmao."

  • Mechanics Reflection: Observations about Undertale acting as a Minimum Viable Product (MVP) for Deltarune have emerged. Fans pointed out that many game mechanics and themes in Undertale echo in Deltarune, such as the mercy mechanic and story elements that can be interpreted in multiple ways.

As one user put it, "The more of Deltarune comes out, the more Undertale looks like a testing ground for it."
