About LumenCast
Place light sources on a grid to illuminate all target cells. Each source emits light in four directions until blocked by obstacles. When two beams cross, the intersection becomes annihilated and cannot be lit. Plan your placements carefully to avoid overlapping rays.
Multiple hand-crafted levels introduce new challenges: obstacles block light paths, and limited sources force precise spatial reasoning. Complete every level without annihilating any target to earn a perfect score. Each puzzle has at least one valid solution.
The dark, minimal interface keeps your focus on the grid. Subtle visual feedback shows lit cells, annihilated cells, and active sources. No timer, no pressure — think at your own pace.
