Today we released an update for PC/Mac and PlayStation to fix a few issues with the game. You can confirm the chapter version number on the bottom right of the file select screen. Changelist Chapter 5 Version 0.0.253 ADDITIONAL CHAPTER 5 FEATURES ・After losing to the Shadow Crystal boss, a Pink Bomb will appear outside the arena. Talking to this bomb allows you to choose "Nicer" or "Meaner". Choosing "Nicer" causes the boss's small bomb attacks to have an indication of where their explosions will target. The bombs will also take 1/6th of a second longer to explode. Choosing "Meaner" causes all of the boss's attacks to deal 25% more damage as well as slightly increases the speed of a couple attacks. The bomb explosion hitbox also activates 1 frame later regardless of difficulty.* * Note: Girls like it when you are better at dodging danmaku. ・Malius now animates when fusing items. FIXED BUGS Chapter 2 ・Removed a softlock caused by disconnecting an audio device during sequences synced to the music. ・Losing against Queen no longer fails to replenish your used items. ・A Downed character will no longer stay Downed after defeating Queen. Chapter ３ ・Fixed a softlock involving getting the Power Croissant and saving Lancer in Board 1 in a specific order. ・Fixed 2 softlocks involving turning enemies into pushable objects. ・Attempted to fix a crash involving Kris being downed when Tenna's final attack starts. Chapter ４ ・Fixed an issue where Susie's magic was erroneously upgraded to BetterHeal upon fighting the boss of the Second Sanctuary. This change is also reflected in Chapter 5 -…

DELTARUNE Chapter 5 v0.0.253 Fixes Softlocks, Adds Boss Difficulty Toggle
Toby Fox's team published version 0.0.253 of DELTARUNE on July 31, 2026, for PC, Mac, and PlayStation. The chapter version number can be verified on the bottom right of the file select screen.
What changed
New Chapter 5 features
After losing to the Shadow Crystal boss, a Pink Bomb appears outside the arena. Speaking to it offers two options: Nicer (boss bomb attacks gain targeting indicators and detonate 1/6th of a second later) or Meaner (all boss attacks deal 25% more damage and a couple of attacks move slightly faster).
Regardless of chosen difficulty, the bomb explosion hitbox activates 1 frame later than before.
Malius now plays an animation when fusing items.
Bug fixes across chapters
Chapter 2: Disconnecting an audio device during music-synced sequences no longer causes a softlock; losing to Queen no longer consumes items without refilling them; a Downed character no longer remains Downed after Queen is defeated.
Chapter 3: A softlock tied to a specific order of collecting the Power Croissant and saving Lancer in Board 1 is resolved; two softlocks involving enemies converted to pushable objects are fixed; a crash when Kris is Downed at the start of Tenna's final attack has an attempted fix.
Chapter 4 / Chapter 5: Susie's magic was incorrectly upgraded to BetterHeal upon fighting the Second Sanctuary boss — this is corrected, and the fix carries forward into Chapter 5. The BlackShard at the cliff is no longer blocked by possessing the BlueRibbon. Spamton's box no longer appears at the Cliff. Players can no longer bypass the chase sequence before meeting the Old Man.
For players who have encountered any of these softlocks or the Susie healing inconsistency, the patch resolves long-standing friction points that could strand progress entirely.

DELTARUNE Chapter 5 Gets Its First Patch, Fixing Saves, Combat, and Collision
A patch for DELTARUNE Chapter 5 — version 0.0.250 — was released on July 22, 2026 for PC, Mac, and PlayStation. The update covers gameplay additions, combat logic corrections, and a notable cluster of bugs involving save data inherited from Chapter 4.
What changed
Additions
A Golden Tenna Statue now appears in Castle Town in Chapter 5 if it was obtained from the Ball Machine in Chapter 3.
Voice Clips can now be permanently re-enabled if the Chapter Boss is lost to while they are disabled — described by the developer as "shoddily added."
Bug fixes
Defeating a Titan Spawn with violence in Chapter 4 no longer incorrectly registers as a "Lost" outcome; a downstream issue where Jackenstein would not appear in Chapter 5 town has also been resolved.
Susie now correctly receives additional magic points in Chapter 5 when the Shadow Crystal boss of Chapter 4 was defeated.
Bugged blank item slots carried over from pre-fix Chapter 4 save files are corrected.
The ZL / L2 gamepad buttons no longer register as only a single frame of confirm input in Chapter 5.
A floor-clipping exploit triggered by opening the ACT menu immediately after fighting three scarecrows is fixed.
The game can no longer be crashed by simultaneously striking an enemy and a Mysterious Statue.
Various exploits allowing movement during combat or with menus open have been addressed.
Certain bullet patterns now correctly award TP when grazed.
Kris no longer remains in a sideways orientation entering the final Chapter 5 cutscene.
The patch note ends mid-sentence on a teased next-patch feature, leaving that detail unconfirmed. For players carrying saves across multiple chapters, the corrections to inherited data and combat state tracking are the most substantive changes here.
