All eventsPlayers around this dateRead on Steam

Thank you for playing Kumitantei: Old-School Slaughter! An update has been released, further targeting optimization and performance alongside some smaller bugs.

Patch Notes

  • Direct3D 12 is now the default renderer. On platforms with additional launch options, Vulkan has been made as the secondary, optional option.

  • Further optimization has been made in regards to rendering, significantly improving VRAM usage and framerate.

  • When explaining Evidence Cards during the Card Battle tutorial in the Prologue, they are now highlighted in the player's hand to point them out.

  • The hitbox of the bed in the Nurse's Office has been adjusted to make it easier to interact with the trash can.

  • A door has been added in the Kitchen to make the exit of the room more apparent.

    • The exit hitbox on the left wall has been removed as well, making the oven easier to interact with.

  • Adjusted Erika's position in the Prize Corner during Free Time to prevent issues where she would suddenly block the camera after spending time with Kaguya.

  • Adjusted the description of the Evidence Card Nyanusofu's Testimony.

  • Adjusted the balancing of some Card Battle Debates during the Clinical Trial.

  • Updated the credits.

  • Fixed an issue where dialogue choices would forcefully select the topmost option when confirming using left click.

  • Fixed an error in the Edit Deck menu where the Suit icons did not animate smoothly.

  • Fixed an issue where saving during the scene in the Cafeteria during night of the second day would permanently softlock that save file by breaking story progression. Save files affected by this bug will function as normal following the update.

  • Fixed an issue where, during Skill Card animations, the card would appear fully white while using Direct3D 12.

  • Fixed a minor issue where attempting to fast-forward while the results screen is being shown would play the effect despite doing nothing.

  • Fixed multiple typos and errors across the script.

  • Fixed multiple voice lines.
