About this game

THE PHOSPHOR REEF — sandbox / horizontal scroller / indirect control. Plant coral spires (towers). They charge over time and transmit light pulses that scatter bioluminescent spores into the current. Spores settle on the reef floor and bloom into new coral. A lumen-fish swims the column on its own, drawn to your most-charged spires; when it arrives it triggers a transmission. You shape the environment; the fish does the rest. The reef grows. There is no failure.
