MirrorLane

Guide a single beam of light across a five-by-five board by rotating its mirrors. Each level starts with one light source on the left edge and one or more crystal targets. Tap a diagonal mirror to turn it ninety degrees, and the beam is recalculated instantly. Light every crystal before your rotations run out, and make sure the beam does not escape the edge of the board. Sixty levels are arranged in four chapters. Early levels use only straight channels, diagonal mirrors and walls. Later levels add one-way filters that let light pass in a single direction, fixed mirrors that cannot be turned, and boards with two or three crystals. Each chapter has a tighter rotation limit, so planning ahead matters more than trial and error. Undo takes back one rotation, and Reset restarts the board at any time. Undo is a safety net for misplaced taps, but it removes the perfect medal for that attempt. When the beam leaves the board or the rotations run out, a dashed line marks the exact cell where the light went off course. The daily challenge offers one level each day, the same for every player. Records show the fewest rotations you have used for each cleared level and for the daily challenge. Medals reward skill. A perfect solution uses the fewest possible rotations without undo. Clear three levels in a row and the next level adds a bonus crystal, where a perfect run earns the master medal. The rule codex explains every tile type, and each chapter's notes unlock as you progress. The design is calm and minimal. Deep blue-gray tones and a clean white beam keep attention on the light path, and shapes as well as colors show walls, mirrors and crystals. The game runs fully offline, and your progress stays on your device.
