How to Play

• Tap a mirror to rotate it 45°. Keyboard: arrows pick a mirror, Space rotates.
• The emitter fires a beam of white light. Mirrors bounce it.
• Light every receiver crystal. The beam passes through receivers, so you can chain them.
• A receiver needs the matching colour: white, red, green, blue.
• Glass filters tint white light. Light of a different colour is blocked by them.
• Rocks and barrels stop the beam.
• Finish in par taps or fewer for 3 stars.
