About This Game

"...Can you hear my voice?"

A faint voice reaches an old communication terminal. You are the only one connected to a child trapped in a closed-off world.

Explore together, in your own words

Instead of choosing from fixed responses, you speak to the children in your own words. Talk, encourage them, solve puzzles together, and search for a way out. Sometimes, the words you exchange can open a path that was once closed.

A small world hiding a greater truth

The story unfolds across three chapters: the Boy's Chapter, the Girl's Chapter, and the Final Chapter. As you explore, the nature of this closed world — and the truth left behind within it — is gradually revealed.

About the use of generative AI

Some in-game images, including backgrounds and props, were created using generative AI and then edited and adjusted.

Google Vertex AI is used to generate the children's responses during conversations.

Further details are provided in the "AI Generated Content Disclosure" section on this page.

Character illustrations and key art are hand-drawn, while the story and music are created by their respective creators.

How Signals work (please read)

• An internet connection is required to play.
• Exploring and talking consume Signals.
• The full game includes 500 Signals, which are expected to be enough to complete the entire story in a typical playthrough without purchasing additional Signal Packs.
• Signals do not regenerate over time in the full game.
• Additional Signal Packs are optional purchases for owners of the full game who want to spend more time talking with the children and explore conversations more deeply.

English language support is planned as a free post-launch update.

AI Generated Content Disclosure

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

Some in-game images, such as backgrounds and props, were created with generative AI (Adobe Firefly) and then edited and adjusted before use. All character illustrations and key art are hand-drawn. The scenario and in-game text are based on human-created concepts and structure; AI was used to assist with early drafts, and all final content was edited and finalized by hand. AI tools were also used to assist programming during development.
