LIGHT IT
A warm, quiet light-up puzzle. No countdown, no pressure — just you, the board, and every corner slowly coming to light. In a hand-drawn, paper-textured world, you place glowing crystals until not a single shadow remains. The rules are simple, yet they hide the kind of logic that keeps you saying "just one more."

How to play
Place a crystal, and its light streams out in straight lines, lighting every cell it passes.
No two crystals may shine on each other — mind their line of sight.
A numbered wall tells you exactly how many crystals belong on the tiles around it.
The goal is simple: light every empty cell without breaking a single rule.
