EchoVector

EchoVector is a spatial logic puzzle game that challenges your geometric intuition. As a light path engineer, you must rotate metal components on a grid to guide a laser beam from its source to the target receiver.

Each level presents a 4x5 grid populated with optical components including single-face mirrors that reflect the beam, total reflection prisms that deflect light at 90 degrees, and barriers that block the path entirely. Later levels introduce cone lenses that automatically redirect toward the target and dispersion glasses that split the beam into multiple paths.

Gameplay is turn-based: tap any component to rotate it 90 degrees clockwise. Each rotation consumes one energy point. When you believe your configuration is correct, press Execute to fire the laser and watch the beam trace its path through the grid. The beam animates along the correct path, lighting up each component it passes through.

Victory is achieved when the beam reaches the target receiver. Performance is rated S, A, B, or C based on how few rotations were used. Bonus energy is awarded for efficient solutions. Running out of energy means you must retry the level.

Levels are procedurally generated, ensuring each playthrough offers a fresh challenge. The game includes progressive difficulty across multiple levels, starting with simple mirror rotations and advancing to complex multi-component configurations with beam splitting.

The game features a dark industrial tech aesthetic with low-saturation backgrounds, fluorescent cyan laser effects, and warning orange energy indicators. All gameplay is fully offline with no permissions required beyond standard app installation.
