UMBRA
Step into your own shadow.
A wordless puzzle museum. Push crates and lamps across the floor, then step into your shadow and walk the wall as a little ink figure, out through the paintings.

The idea
One room, seen two ways
No words, no tutorial. Three things to know, and forty-two rooms to learn what they mean.
I
The floor
Seen from above. Walk, and push heavy crates and lamps. Plates want weight; gates want plates.
II
The wall
Seen straight on. Every lamp throws every shadow here, bigger the nearer it stands to the light.
III
Step in
Become a little ink figure on the wall. Walk the tops of shadows, climb one step at a time, leave through a painting.
Two views, one room.
The floor from above, the wall straight on. Every lamp throws every shadow, and nearer the lamp means bigger.
Stand on yourself.
Step into your shadow and your body stays behind, still blocking the light: its shadow is the pillar you stand on.
Forty-two paintings.
Hand-designed and solver-checked. Every piece in a room is there for a reason, and the shortest way through is the clever one.
No words at all.
No tutorial text, no dialog. Each wing teaches its idea with a room, then turns it inside out.
Perspective is the puzzle.
A lamp's height is the horizon. Low lamps make giants; high ones shrink things as they near them.

Light and perspective. Walk toward the lamp to stand taller.
Night
Weight. Your body holds a plate down while you're on the wall.
Dawn
Lanterns. Move the light, and every shadow moves with it.
Garden
Hanging cages cast floating bridges and ceilings.
Library
Painted stones stay on the wall between trips, and ride shadows up.

Controls
Mouse first, keys too
