Water Official

Water Official: a light-routing puzzle with 500 hand-tuned levels and steadily rising difficulty. Rotate mirrors to bend each beam, pass it through crystals to tint it, and light every receiver with a matching color. Every level is a little harder than the last (par never drops; mirrors, beams, crystals, walls and decoy mirrors keep growing), with guaranteed-solvable levels, stars and saved progress, an automatic attract demo, sound, and a fully English interface.
