No combat. Only light, shadow, and the blind spots she drew. SHORT PITCH For eleven years, Margaret Vane sat at a government records desk and decided what the country was allowed to see — and, more quietly, what could go unwatched. She drew the blind spots herself. Then she reported a ledger she was never meant to read, and by morning she had been struck from every register that ever held her name. Filed Under No One is two halves of one story: a novel that walks her to the fence and stops — and a top-down stealth game that is the night the book refuses to narrate. You cross the building she used to run, cone by cone, breath by held breath, exploiting the surveillance she designed, to recover three small things with her name still on them. It runs free in a browser, on an engine built from nothing, and there is no fighting in it — only what the light touches, and what it doesn't. ================================================================================ HOW IT PLAYS (no combat, no weapons, no health bar) - Light is the whole game. Guards see in hard wedges of light, line-of-sight checked tile by tile; corners block sight. To win, you are simply never seen. - The shadow rule. Step onto a shadow tile and a guard staring straight at you cannot see you. Binary, legible, ruthless. - One detection meter, shared by the floor. Fills in under a second of unbroken sight, drains the instant you break it. Fill it and you're taken — no second chances. - Sound vs sight. Sound only ever sends a guard to LOOK; only being SEEN raises the alarm. Run and you're fast and loud; sneak and you leave nothing. - Tools. A deliberate knock lures a patrol; a corner radar shows guard facings while calm — and dissolves to static the moment you go loud. - Controls. Arrows / WASD, run on Shift, action on Space / Z. Full rebinding; gamepad. SOUND — entirely procedural, even the music (synthesised live in code, no audio files). A cinematic menu drone; then silence on the floor, where sound marks change — papery footsteps, a rising "?" chirp, a two-voice "!" stab panned toward the guard who made it, and a heartbeat tempo-locked to the detection meter (60-180 BPM as capture nears). LOOK — drawn in code, in the playfield: no textures, no sprite sheets, no loaded images; every wall, cone, shadow and figure rendered live from Canvas 2D primitives, the player and guards hand-pixelled. Dark grids, pale cones, true-black shadow, one rationed amber signal — of a piece with the novel's cover. The form is the theme. ================================================================================ CHARACTERS (spoiler-safe) - Margaret Vane — twenty-seven; eleven years at the records desk. She maps the blind spots of others and never once turned the lamp on her own. Her face is never shown on any public-facing surface — the work sells the question of who she is now, not a portrait. - The Director — the one figure who never leaves his post, who still watches his own door in the dark at the end of the last night; the only man who would know her if he turned around. The game never shows you whether he does. TAGLINES / PULL-QUOTES - She kept the country's secrets. The country kept one — about her. - Erased on paper. Returning in person. - Stay in the dark and you are a rumour. - What is seen is recorded. What is not seen did not happen. - The most dangerous thing in the building is a rubber stamp. - The book stops at the threshold. The game is the night she goes back in. ================================================================================ WHO MADE IT DS Laboratory is a one-person studio in London. Filed Under No One — its engine, its prose, its levels — was designed, written, and directed to one standard by one person, David Silva, with AI carrying out much of the execution under that direction. The studio states this plainly: the decisions, the testing, and the bar are one author's.
