Our take on P.I.

Rather than placing players in a conventional horror investigation, P.I. frames the story as an ongoing home livestream. The broadcast becomes the structure for revealing identity concerns, daily events, and multiple endings, replacing a more traditional sequence of exploration and encounters.

What is P.I.?

P.

I. is an interactive fiction game about a female streamer broadcasting from home while waiting for her partner to return. Concerned about a recent streamer serial murder incident, she gives viewers a tour while avoiding details that could reveal her identity. As the broadcast continues, strange events begin unfolding in her everyday life. Live streaming is the central theme of this psychological horror science-fiction story.

The game takes about 60 to 120 minutes and includes multiple endings. Players can view all endings without finishing the game. Progress is saved automatically when a streaming day is cleared, allowing play to resume from that point. Camera shake can be disabled, and the game can be reset by pressing the 9 key three times.
