About This Game

Sato Killing Time Chat.exe is a short-form ARG (Alternate Reality Game) mystery where players communicate with a mysterious girl named "Mina" through a chat interface. This isn't just a game inside a window—it’s an experience that bleeds into your real world.

Players launch a specific chat app on their PC and exchange messages with a girl named "Mina." An outcast at school and estranged from her family, she reaches out to you with a simple request: "Kill some time with me."

■ Story Progression via Chat UI
The game features a realistic messenger app interface. Through your conversations with Mina, you will gradually uncover the truth. The responses you receive adapt based on your own replies.

If I tell Mina something she dislikes, she might start keeping her distance...?

■ Web Browser Integrated Gameplay
Investigate a web of multiple fictional pages—furniture stores, news sites, social media, and corporate homepages. Everything is a clue leading to the "answer," from hidden codes and names to a single sentence in a comment section.

■ "Selfies" as Rewards
When you clear specific puzzles or phases, Mina—who is fully convinced of her own cuteness—will send you selfies as a "reward." Is this genuine affection, or is it manipulation?
