Deltarune exists in the shadow of Undertale and uses that shadow as a storytelling device. Toby Fox’s follow-up takes familiar characters and places them in a new context, where Kris, a human in a world of monsters, falls into a Dark World that demands heroes. But something is off. The game keeps hinting that the player’s control over Kris isn’t as natural as it seemed in Undertale, and that tension between player and character drives the experience into territory its predecessor never explored.
The community treats Deltarune with the same obsessive analysis it applied to Undertale, but with an added layer of anxiety about what the game is building toward. Two chapters are available, and the theories about where the story is heading are endless.
The Evolution of the Formula
The combat system improves on Undertale’s already excellent foundation. Bullet-hell defense sequences are more complex and creative, with boss fights that rank among the best in the genre. The addition of party members opens up tactical possibilities during both fighting and sparing, and the TP system, which rewards skillful dodging with resources for special abilities, creates elegant risk-reward dynamics.
The writing is Toby Fox at his best. Dialogue is funny, surprising, and frequently touching. Characters like Ralsei and Susie develop in ways that feel organic, and the game’s humor coexists with genuine emotional depth without either undermining the other. The shift from Undertale’s ensemble cast to a focused party dynamic gives relationships more room to develop.
The meta-narrative elements are the game’s most fascinating aspect. Deltarune repeatedly questions the player’s role, hinting that your control over Kris might be an act of possession rather than identification. Chapter endings, particularly Chapter 2’s, land with unsettling force because they confront assumptions that most RPGs never acknowledge. The game is building toward something, and the anticipation is part of the experience.
The music is exceptional. Toby Fox’s compositions range from battle themes that demand replay to ambient pieces that establish mood with precision. The soundtrack is varied, emotionally intelligent, and consistently memorable.
An Incomplete Experience
The biggest limitation is structural: only two of a planned seven chapters are available. Evaluating Deltarune means evaluating an incomplete work, and the strengths and weaknesses of the existing content may look different once the full game arrives. Players who want a complete experience should know they’re buying a prologue, and the remaining chapters have no confirmed release timeline.
The choice system works differently from Undertale, and this is both interesting and potentially disappointing. The game suggests that your choices may not matter in the way Undertale’s did, which is thematically provocative but can feel disempowering for players who loved the original’s emphasis on player agency. Whether this setup pays off depends on chapters that don’t exist yet.
The two available chapters, while excellent, are relatively short. The free first chapter and paid second chapter together provide around eight to ten hours of content. The investment is minimal, but so is the current scope.
Some players find the Dark World segments more engaging than the Light World sections. The town exploration between Dark World adventures can feel slow compared to the heightened drama and combat of the main storyline. The contrast is intentional, building normalcy before disruption, but the pacing suffers in the quieter sections.
The Player Is Not in Control
Deltarune’s most radical idea is that it might not be your story. Undertale put extraordinary weight on player choice. Deltarune systematically examines what it means when a game removes that weight while making you believe you still have it. It’s a game about control, and the uncomfortable realization that the control you’re exercising might be over someone who didn’t consent to it. Whether this idea reaches its full potential depends on the remaining chapters, but the foundation is thrilling.
Should You Enter the Dark World?
If you loved Undertale, Deltarune is essential, with the caveat that it’s unfinished. The available chapters are excellent, and the Chapter 1 being free means there’s no barrier to trying it. Players who need complete experiences or who don’t enjoy meta-narrative games should wait until the full game exists. For everyone else, Deltarune’s first two chapters contain some of the best writing, combat, and music in the indie RPG space, and the promise of what’s coming makes the wait feel worthwhile even when it’s painful.
The Verdict on Deltarune
Deltarune is an extraordinary work in progress. Its combat is tighter than Undertale’s, its writing is sharper, and its thematic ambitions are more unsettling. The incomplete release structure is a genuine limitation that prevents full evaluation, but what exists is among the best content in indie gaming. It’s a game that’s simultaneously a sequel, a commentary, and a mystery, and the community’s obsessive engagement with its implications speaks to how effectively it’s building toward something that could be remarkable. The question isn’t whether it’s good. It’s whether the destination matches the journey.
