How to play

Tap empty cells (paths) to place glowing firefly lamps.
Every path must be lit by a lamp's rays (which spread left/right/up/down until blocked).
No two lamps can see each other directly — walls and grid edges block sight lines.
Tap again to remove a lamp. Solve when all paths glow and no two lamps conflict.
