The Case Files
Adult interactive detective mysteries from Plyven. Rainy cities, open dossiers, and freeform investigation — you type (or speak) what you do next.
What it is
The Case Files is a noir-toned mystery game for adults and teens. Each case is an AI-driven investigation: move through locations, question people, inspect clues, and close the file when you are ready to accuse. Your partner Kai narrates and reacts in character.
How a case works
- Open a case file and enter the scene.
- Investigate freely — no fixed dialogue trees or tap-to-win options.
- Uncover people, places, and clues as the story unfolds.
- Submit your theory and get a graded debrief when you solve.
Who it is for
Players who want mature mystery atmosphere, sharper stakes, and a detective fantasy that feels written with them — not a kids club adventure. Looking for the family game instead? See Mystery Club.

FAQ
- Is this the same app as Mystery Club?
- No. The Case Files and Mystery Club are separate Plyven games with different tone, content, and store builds.
- Do I pick from multiple-choice options?
- No. You describe actions in freeform text (and voice where supported). Kai responds as your case assistant.
- Is there a subscription?
- Plans unlock higher case and audio limits and saving progress. Billing on web uses Stripe; native builds use the app stores via RevenueCat.
