About This Demo

You wake up in a morgue. The manual lists 4 rules. You only need to remember one thing: speak and you die.

Your microphone monitors your volume in real time—any sound above the threshold will end your game. You can test, you can stay silent, you can verify. But every sound you make could bring you closer to the truth—or further from it.

In this demo, you will experience:

• Sound Equals Death: Your microphone monitors your volume in real time.
• False Rule System: The manual's content may not be trustworthy.
• Second-Chance Mechanic: The first death is not the end.

The demo takes about 5–8 minutes to complete. The full version contains more content, and the real exit.

A microphone is required to play. Headphones are recommended for the best experience.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

For the store page and in-game multilingual texts, the Simplified Chinese version was written entirely by the developer. All other languages (Traditional Chinese, English, Russian, French, Japanese, and Latin American Spanish) were translated with the assistance of generative AI. All core content of the game (mechanic design, scene construction, character and story development, art assets, and audio) was independently created by the developer. AI was used solely for language localization and did not participate in the generation of any other content.
