Steam Patch Notes
Official update history
On the site: Build 24484059
Up to date
Version 0.0.253
Jul 31, 2026
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 - Susie's healing will no longer be improved if you didn't defeat the ShadowCrystal boss. (Although the name of the spell is the same either way now)
・You are no longer prevented from getting the BlackShard from the cliff if you have the BlueRibbon.
・Spamton's box will no longer appear at the Cliff.
・You can no longer avoid getting chased before meeting the Old Man for the first time.

・Fixed a few minor issues.
Chapter 5
・Fixed a softlock introduced by a previous bug fix in the Garden room with the light pillar.
・Fixed a crash introduced by a previous bug fix where you could defeat Yellow with violence using a precise set up.
・Fixed a bug where you can walk around with the dialogue box open in the room where you fight Sheary.
・Removed Honey Toast from the inventory when sleeping in the bed at the beginning of the Chapter.
・Fixed dozens of minor bugs and visual issues.
Thanks for your patience while we adjusted the game. We will now return to focusing on developing Chapter 6. We have no current plans for another patch unless any additional issues arise.

CLARIFICATION OF PREVIOUS PATCH NOTES
A modification to the chapter boss which makes the battle easier was mentioned recently.
To be clear, this battle only becomes extremely slightly easier each time the player loses from 6 times
to a maximum of 16 times in a single gameplay session. If you lose to the boss 5 times or less, this
change has no effect on you, and even losing to him 6 or 7 times has so little of an effect that the
average player would not notice a meaningful difference.
We will continue to address issues as quickly as we can.
Thank you for your patience and for playing the game!
Hey guys, one more small patch here. As we seem to have covered many common crashes and softlocks, we'll be taking our time with the next patches.
- Fixed a bug where losing to the last boss of the chapter, leaving the area without saving, then getting a game over elsewhere would result in the file failed to load (dogcheck) screen.
- Fixed a crash in a room where you can spend Pink Coins.
- Attempted a fix for a crash when lyrics are displayed onscreen.
- Fixed a softlock when entering a room where you are blown upwards by wind, without dashing.
- Fixed a softlock where a large yellow gun could move offscreen forever.
- Fixed a softlock where a giant pair of glasses could become invincible forever.
- Fixed a softlock in a certain Festival after talking to the guy who regrets buying round things, saving, then reloading the game, then talking again.
- Added a failsafe to the scissor cutting ACT where the ACT will end automatically if enough time passes without initially moving.
- Sprites no longer disappear when trying to put your hands in the grape I mean eyeball bowl.
