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.
