What is Salt Line?
You have no weapon. Your only verb is enclosing space.
Salt Line is a physics containment game. A ghost is not a sprite but a shoveable blob that drifts toward its haunted props and fights back against anything that corners it. Hold anywhere to raise a salt cell, drag it across the room to wrap the shape, and lift your finger to seal the cell. Hold too long and the line burns out. Swing it too wide and it tears. Release while the shape is still clawing at the rim and it snaps shut on empty paper.
Every room is generated from a seed: the props, the blob's size and speed, the ring you can draw, and how hard it resists all come from a parameter set chosen by a solvability assertion, so no room is hand-placed and no room is unwinnable. Rooms get tighter as you descend, and the ring gets shorter limbs.
Wrap the loose sigil together with the ghost for a bonus salt mark. Six rooms per run, retry instantly, and the same seed always rebuilds the same hunt.
