What the developers have to say:

Why Early Access?

“The Last Question is built around AI character interaction and detective reasoning. We want players to experience the current playable cases, dialogue system, clue organization, and timed exploration before the full release.

Because the experience depends heavily on how real players ask questions, investigate, and reason through cases, Early Access will help us improve case pacing, AI character responses, clue guidance, UI interaction, and content balance.”

Approximately how long will this game be in Early Access?

“We expect Early Access to last around 6 to 12 months. The exact duration may change based on player feedback, content development, and system improvements. Our goal is to leave Early Access once the core gameplay, case content, stability, and overall experience reach our full release standard.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to include more original official cases, more case types, a more complete investigation flow, and richer character interactions.

We also plan to add a custom case creation feature. Players will be able to design their own case settings, characters, clues, and reasoning paths, then publish their completed cases to the in-game community for other players to experience, discuss, and provide feedback.

The full version will also continue improving AI dialogue quality, clue and timeline systems, timed map exploration, task guidance, ending judgment, UI presentation, and overall stability.”

What is the current state of the Early Access version?

“The current version already includes playable core content. Players can enter cases, question characters, investigate clues, organize testimony and timelines, and use reasoning to progress through cases. Some cases also include timed map exploration, item collection, NPC schedules, and ending judgment.

The game is still in active development, and some content, UI, balance, and AI response quality may continue to change and improve.”

Will the game be priced differently during and after Early Access?

“During Early Access, the game will be sold at a lower price than the full release version. When the full version is released, the price will increase.

This price increase will reflect the addition of more official cases, expanded gameplay systems, custom case creation features, community publishing features, and improvements to overall stability, UI presentation, and content completeness. We will notify players in advance through Steam announcements before the price change.”

How are you planning on involving the Community in your development process?

“We will actively follow Steam community discussions, reviews, and player feedback. Feedback on case experience, AI dialogue, clue design, difficulty, UI, and stability will help guide our development priorities.

Player feedback will help us improve clue guidance, adjust reasoning difficulty, fix issues, refine character responses, and plan new cases and gameplay features.”

About This Game

Ask Anything. Trust No Answer Completely.

In The Last Question, you step directly into a series of unresolved mysteries.

Question the people involved, search important locations, collect evidence, organize timelines, and find the contradiction that breaks each case open. In the end, the truth must be reconstructed through your own reasoning.

There is no predefined list of questions waiting for you.

What you ask is entirely up to you.

Do Not Choose a Line. Ask the Question Yourself.

Type what you want to ask and speak naturally with the people involved in the case.

Begin with an overlooked detail, pursue a suspicious statement, or present evidence and confront someone with a contradiction.

Every character has their own identity, history, motives, memories, and secrets. They may confess, evade, conceal information, or lie.

There is no single interrogation order. You decide whom to question first, whom to trust, and which detail to pursue next.

An Answer Is Testimony, Not the Solution

Everything an NPC tells you is only one piece of the case.

A response may reveal a new clue—or deliberately lead you in the wrong direction. Important information must be checked against physical evidence, other statements, times, locations, and movements.

Do not wait for someone to volunteer the truth.

Observe their reactions, follow up on details, find claims that cannot all be true, and use evidence to break through the lie.

Investigate a World That Keeps Moving

The investigation does not end at the dialogue box.

In some cases, time continues to advance and characters follow their own schedules. Move between locations, search scenes, collect items, complete objectives, and decide where you need to be—and whom you need to find.

Every movement and decision may cost valuable time. Miss a person and you may lose an essential statement. Overlook an item and the entire chain of reasoning may remain incomplete.

  • Explore Locations:Move through the case map and investigate different areas.

  • Track Characters:Compare statements against NPC locations and schedules.

  • Collect Items:Discover, use, or combine objects connected to the case.

  • Manage Time:Decide what to do before the next critical event occurs.

Turn Fragments into the Truth

Use the case board to organize relationships, testimony, items, and important clues while recording your own analysis.

Bring scattered information together and reconstruct the order of events:

  • Who had a motive?

  • Whose timeline does not hold up?

  • Which statements can be independently verified?

  • Who is hiding the truth—and why?

  • What decisive detail have you overlooked?

In the end, you must submit your own judgment and stand behind your conclusion.

Different Cases. Different Rules.

The Last Question features multiple original case structures.

One mystery may confine you to a closed room filled with suspects. Another may place you in a living world where you must investigate locations, follow characters, collect items, and respond to approaching events before time runs out.

Cases may include:

  • Free-form questioning and testimony comparison

  • Scene investigation and clue collection

  • Relationship and motive analysis

  • Timed map exploration

  • NPC schedules and movement

  • Item collection and combination

  • Case-board and timeline organization

  • Critical choices and final judgments

AI Plays the Characters. You Solve the Case.

NPC dialogue is generated in real time and constrained by each character’s identity, memories, motives, established case facts, current game state, and content-safety rules.

Ask the same question in a different way and you may receive a different reaction. But the AI provides character testimony and behavior—not a system-approved solution.

You must still investigate scenes, collect evidence, verify statements, and complete the final deduction yourself.

Key Features

  • Live AI Character Dialogue:Type your own questions without relying on a predefined list.

  • Open-Ended Investigation:Choose your interrogation order, route, and next action.

  • Dynamic Character Reactions:NPC responses reflect their settings and the current state of the case.

  • Multiple Case Structures:Experience interrogation, exploration, timed action, item collection, and final judgment.

  • A Complete Deduction Process:Organize relationships, verify testimony, expose contradictions, and submit your conclusion.

  • Original Mystery Stories:Investigate cases built around identity, secrets, relationships, desire, and human nature.

Evolving Throughout Early Access

The current version includes complete playable official cases and the core systems for free-form questioning, map exploration, clue collection, case-board organization, timelines, and final judgments.

During Early Access, we will continue adding original cases and case formats while improving deduction difficulty, AI character behavior, case pacing, interface interactions, and overall stability based on player feedback.

The truth will not volunteer itself. What will your last question be?
