About Object Impermanence Demo

Your science expedition is sent to investigate a planet adrift in a vast void, where a ship malfunction leads to a rough landing. With your vessel unable to carry you home, the ruins ahead call to you, their doors opening only to those who see the patterns of the decayed reality, and who learn to use them to their advantage.

A world without object permanence

To progress you need to interact with the old machines across the ruins, and the world around you, but the decaying reality makes them behave in strange ways when you look away.

When something leaves your field of view, some things no longer:

Solve mind-bending puzzles by using your vision to control what exists and what doesn't. Doors open, elevators move, lights shine, fans blow, and critters scurry only when you see them.

For something to exist, it needs to be remembered, and everything that exists, eventually degrades.
