About this game

This is a mystery game where you investigate a single illustration and deduce the truth of a case from evidence and testimonies.

"Illustration Investigation" has been completely revamped. New cases and color illustrations have been added, bringing the total to 50 cases. As a detective, observe the crime scene, find inconsistencies and clues, and deduce the culprit.

This Renewal
- Revamped the design of the title screen and each game screen
- Supports zooming in and out of the crime scene
- Improved visibility of investigation items and suspect information
- Improved readability of the deduction screen and case explanation
- Adjusted tap detection to make it easier to find evidence
- Revised the text, choices, and images for each question
- Improved the stability of ad display and purchase restoration

How to Play
1. Check the question text and the illustration of the crime scene
2. Zoom in and out of the screen to look for inconsistencies and evidence
3. Organize the investigation items, suspect information, and statements
4. Use lateral thinking and observation skills to narrow down the suspects
5. Select the answer on the deduction screen and confirm the truth in the case explanation

The crime scene can be freely zoomed in to check details, and zoomed out to review the relative positions of people and objects. By comparing the investigation items found, suspect information, testimonies, and statements, the background of the case that cannot be seen from the illustration alone will become clear.

On the deduction screen, you can consider the choices while reviewing the evidence you have collected. The case explanation after answering is also easier to read, allowing you to check which inconsistencies led to the truth.

Features of this game:
- An illustrated mystery game featuring 50 different cases.
- An observation game where you search for evidence in a single picture.
- A detective investigation game where you can enjoy finding the culprit and solving the case.
- A fast-paced structure that allows you to play each case in a short amount of time.
- A hint function that can be used for difficult problems.
- A brain game that tests your reasoning, observation skills, and lateral thinking.

- Like puzzle-solving and mystery games.
- Want to find inconsistencies in illustrations.
- Want to deduce the culprit from evidence and testimonies.
- Like mysteries where you uncover the truth behind murder cases.
- Looking for a short investigation game.
