About Schrödinger's Call
Schrödinger’s Call places players in a fleeting, picture‑book world where the moon is about to fall and only twenty‑one nanoseconds separate life from death. Mary awakens with no memories, guided by a cat named Hamlet, and becomes the “World’s Last Confidant,” holding a single phone that connects her to lingering souls.
Through each call, Mary records unfinished words and regrets, inviting players to reflect on what truly matters. The game’s gentle narrative unfolds chapter by chapter, offering a quiet meditation on endings and the power of a final conversation.
01 / THE GUIDE
Story Overview
The narrative centers on Mary, who wakes in a strange room with her memories erased. Guided by Hamlet the cat, she learns she must listen to voices trapped between life and death as the moon falls.
Each phone call reveals a lingering regret or unsaid feeling, allowing Mary—and the player—to walk alongside these souls in their final moments before the world ends.
- Pay close attention to the tone of each voice; it hints at the emotional weight of the regret.
- Consider the timing of each call; the story emphasizes the brief window before the ending.

Phone Call Mechanics
A single phone is the core interactive element. Players pick up calls left unfinished by the falling moon, hearing voices of those still trapped between life and death.
As Mary notes down each lingering regret, the game progresses chapter by chapter, linking each conversation to the overarching theme of final words.
- Listen to the entire call before noting regrets; details often emerge later in the dialogue.
- Use the notes as a personal reflection tool to deepen immersion.
