Thank you for playing Kumitantei: Old-School Slaughter! An update has been released, fixing and adjusting multiple aspects of the game.

Patch Notes

  • Added the ability to fast forward through dialogue, mapped to Control and Right Bumper by default

  • The censor from the Sensitive Language Filter option has been slightly adjusted

  • Tutorial popups now prevent advancing for a brief amount of time to avoid situations where important information is accidentally skipped through mashing

  • Following spending time with a character during Free Time, Himari is now transported to her dorm

  • During Merlite and Cosmidors in the Clinical Trial, it is now possible to re-read the tutorial by pressing F1

  • Removed fall damage in the Clinical Trial version of Merlite

  • The redundant lives counter in the Clinical Trial version of Cosmidors is now hidden

  • Increased the movement speed in Cosmidors by 20%

  • During Card Battle Debates, the opponent's dialogue can no longer be interrupted by another line of dialogue

  • Fixed an issue where entries in the Message Log would not update automatically when switching language in the middle of dialogue

  • Fixed an issue in the Card Battle tutorial in the Prologue where a confirm input would occasionally double and play a card too early during the sequence or an Evidence Card could be played instead, resulting in a softlock

  • Fixed an issue in the Kitty Catcher where the chance of missing a selected tile was lower than intended

  • Fixed an issue where Shigure lost two Trust levels when given a Chicken Bucket instead of gaining two

  • Fixed several issues where the note in the pause menu did not update when needing to return to Himari's Dorm

  • Fixed an issue where dialogue blips from the "No Voices" setting would play during dialogue in a Card Battle despite the setting not being set

  • Fixed an issue in Cosmidors where taking damage resulted in a permanent softlock

  • Fixed an issue in Cosmidors where enemies would occasionally spawn without a letter

  • Fixed several issues in Cosmidors and Merlite where sound effects did not play correctly

  • Fixed an issue during the Closing Argument puzzle where mouse input took priority over directional inputs, resulting in behavior where changing selection would not work as expected

  • Fixed an issue where the Closing Argument UI would break when running out of time, allowing dialogue to be advanced while solving the puzzle

  • Many gameplay adjustments have been made to the Card Battle Boss Phase

    • Greatly reduced the amount of time the segment goes on for

    • Increased hand size during this segment from 5 to 7

    • The opponent now displays their Active Card and changes it at the start of each of their turns

    • Combos must be started and continued with the same rules as the normal phase: playing a card whose Suit beats the opponent's, or by matching the number of your previously played Debate Card. Continuing a Combo can only be done by matching the Suit of your previously played Debate Card
