About This Demo

Flat in shadow. Tall in light.

Shine to raise. Absorb to flatten.

A first-person puzzler for the people who still keep a portal gun, a camera, and a perspective shift bookmarked in their library.

Shine light to give shadow weight.

A flat square unfolds into a staircase. A fragile outline turns into a towering pillar. Light grants mass, collision, gravity — and once it's solid, you climb it, push it, drop it.

Absorb light to switch Physics off.

A rolling ball lies still. A wall becomes a doorway. Mass vanishes — and what blocked you now lets you through.

The mechanic keeps growing.

Mirrors duplicate. Lenses resize. Merging fuses two forms into a new one.

Three chapters deep. Five mechanics that learn to talk to each other.

The deeper you go, the more the rules combine.

Built to escalate — never just adding, always recombining.

3 chapters · 6+ hours · 60+ Stages.

A world that watches you solve it.

An unnamed Administrator built this place to be flawless. A marble museum gives way to an office that repeats one hallway too many times, and finally to a black-and-white space where memory leaks through the walls. The architecture is your second puzzle — read it carefully.

Watch out for the beings hiding in the shadows...
