About this game
◆ Update Status (as of June 3, 2024) ◆
We heard your feedback that the game felt too luck-based, and so we have rolled out an update on May 27 that addresses balancing issues and tweaks luck-based features of the game.
On June 3, we have also released an update that added the ability to redraw cards at the start of each case, which allows players to have a better ability to strategize and take control of their playthrough. This should make it less likely for players to run into situations where they are forced to rely on pure luck.
◇ ◆ ◇ ◆ ◇ ◆ ◇ ◆ ◇ ◆ ◇ ◆ ◇ ◆ ◇
Would you like to play a game of deduction?
Before you are the testimonies from the 3 suspects of a murder case.
Among them is a lying murderer...
X: Obviously, the culprit is Y.
Y: I'm not the culprit.
Z: X and I are not the culprit.
Could you quickly tell who the murderer was?
The job of a detective reaper is simple: get testimonies from the suspects, deduce the culprit, and execute them with your own two hands.
Culprits always tell lies, and the innocent always tell the truth.
If you choose incorrectly, you will be deemed unfit to be a detective reaper... and yours will be the next life to be harvested.
This is a roguelite deduction adventure game.
Every murder case you have to solve is randomly generated on a game board, and if you fail (and get a Game Over), you will have to start all over again.
No two cases are entirely the same, and there is no single correct way to proceed.
Rack your brain and expose murderers, one after the other.
How long do you think you can last...?
You can use cards to obtain new testimonies, among other things, in order to ensure a successful deduction.
However, cards cost money to play.
If you overuse them and run out of money, you might struggle with a tougher case later.
You can earn money by successfully executing culprits, and bonuses are offered to those who identify culprits efficiently.
Will you use all your cards to make sure you have the right suspect, or will you save up your money for later?
As a detective reaper, it's your responsibility to spend wisely.
You can unlock new cards based on how much money you spend on each run, so you could also spend as much as possible in earlier runs to unlock more cards more quickly.
After solving each case, it's time to decide your next move.
Choose between Deduction, Shop, Treasure, and Random tiles to move forward on the board.
■ Shop
Here is where you purchase items and cards, or pay to recover some HP.
Use the hard-earned money you've saved up from previous deductions to gain an upper hand.
There are also Demerit Cards and cursed items which have detrimental effects... but the shop will pay you to take them off their hands!
■ Treasure
Here, you can open a treasure chest and obtain a random item.
There's a chance the item inside is cursed, though...
■ Random
Who knows what will happen? Test your luck!
■ Deduction
There has been a murder! Find the culprit(s) and execute them.
There are 3 types of deductions: Normal, Difficult, and Arduous, in order of difficulty. The last tile of every stage will always be an Arduous Deduction, so make sure you're prepared to tackle it by then!
After you successfully solve an Arduous Deduction, the detective reaper's story progresses.
Every mistake can be fatal. Solve the cases the best you can to reach the end of the story.

Patch Notes [2024/06/20]
Hello everyone, We have released a new major update that introduces new cards, a new game mechanic, and UI and game balance improvements. Please read the following patch notes for more details on the update. Even if you've already beaten the game, please try out the new, more polished version as well! New Cards: Faze and Deceit Faze (6G) - Get true testimony even if target is a culprit Deceit (6G) - Get false testimony even if target is innocent Both cards will appear as rewards upon solving a case and in shops. They can be used to find inconsistencies in a suspect's testimonies and determine whether they're innocent or not. New Feature: Dice Reroll You may now spend 7G to reroll the dice once per deduction in Nanase's Story. Crime Scene UI Visibility Improvements Adjusted the position of room names to make it clearer which room it labels. Removed the dots under the "?" icons used to represent suspects. Now the icons will be differentiated by color instead. Suspect locations correspond to the position of the bottom of the "?" icon. Slowed down the speed at which suspect icons move when switching between points in the timeline. Balance Improvements Increased the upper limit of testimonies given by suspects in Nanase's Story from 2 to 3. Increased the amount of HP healed and maximum HP gained from certain cards. Raised the maximum amount of HP recovered and money gained from events. Shortened the time limit in Hard Mode to the following: Natalie's Story - Chapter 1: 160 seconds / Chapter 2: 180 seconds / Chapter 3: 200 seconds / Chapter 4: 220 seconds Nanase's Story - Chapter 1: 180 seconds / Chapter 2: 200 seconds / Chapter 3: 220 seconds / Chapter 4: 240 seconds Bug Fixes Fixed an issue in the English version where suspects would sometimes give the wrong testimony when asked to provide one pertaining to their location at a certain point in time.
