Rules
- Tap a round turntable to turn its mirror a quarter turn. With a keyboard, focus it and press Enter or Space; arrow keys move between turntables, Ctrl+Z undoes.
- Bolted mirrors on square plates never move. Wooden blocks stop the beam.
- Light lens 1, then 2, and so on, each once. Then reach the sensor from its open side.
- No move limit and no lives. Undo takes back one turn; Restart resets the board.
