Mnemosyne Protocol

The Mnemosyne Protocol is a gravity game. You float through space, pulled toward signals, collecting gems along orbital arcs.

Three orbits around the right star and the game changes. A name appears. A journal unlocks. Someone volunteered to have their entire life recorded as the last archive of a dying civilisation, and every piece of this world is one of those memories. A park bench. A neighbour in a corridor. A ripped drawing. Eight names on a wall.

There is a story in journal entries hidden throughout the physics of the world. Some unlock through orbiting. Some through speed. Some through stillness. One requires you to be floating, weightless, at the exact moment the sky turns red.

The game has multiple endings. You'll know the real one when you find it.

Unique concepts

1.  Journal as hint system and narrative - 58 entries, all unlocked by solving puzzles. The journal persists across runs. The story is made of hints, and the hints form the story.

2. Proximity based layered music - Each star plays a different instrument. Move closer and you hear it louder. All instruments layer into a coherent composition.

3. Gravity-led movement - You're always being pulled by multiple stars simultaneously. Skill is learning to use competing forces to slingshot, orbit, and decelerate. Every run is a physics problem.

4.  Micro-puzzle structure - No levels, no checkpoints. The entire game is one continuous space. Each puzzle is a specific physical condition to achieve inside that space. Puzzle completions unlock new puzzles and persist across runs.
