Sinclair's Notebook

A literary mystery game where you become Sinclair.
Sinclair and Demian are irreplaceable friends who understand each other like no one else. On the day Sinclair dreams of receiving Demian’s notebook, ominous dark clouds cover the sky, and people suddenly become impulsive and violent, their eyes stained a maddening red. In an instant, the world descends into complete chaos.
Sinclair opens the strange notebook Demian once gave him. From within it, a glowing blue bird bursts forth and flies toward Demian’s house. Carrying only the notebook, Sinclair follows the blue bird—the beacon of light Demian left behind—and sets out on a perilous journey.

About the Game

Sinclair’s Notebook is a point-and-click mystery thriller visual novel that reinterprets Demian, Hermann Hesse’s coming-of-age classic. One day, the world of evil—filled with blood, darkness, and immorality—emerges with ominous storm clouds and begins to consume even the world of good.
In this crisis, Demian, Sinclair’s one true confidant, has vanished. Your goal is to follow the beacon of light, find him, and uncover the truth behind what has happened.
Set against the literary atmosphere of the 1910s, the game delivers poetic emotion and delicate portrayals of the inner self inspired by the original novel. Whether you have read Demian or not, you can enjoy the story through an immersive choice-driven narrative. Choose Sinclair’s words and actions yourself, and draw closer to the truth.

Gameplay

Ordinary life is gone. Explore the map to uncover clues that will lead you to Demian and gather the evidence needed to support them, recording everything in your notebook.
Once you have collected enough clues and evidence, you must combine what you have gathered in the notebook and solve the situation at hand. In a world brought to a standstill, Sinclair is not simply trying to identify a criminal and bring them to justice. He must save those consumed by madness, resolve conflicts among the people entangled in each case, and investigate situations that defy all understanding.
The game also features puzzles that are approachable even for players who are new to mystery games.
