Bioluminescence in the deep. Soft lights drifting through darkness, pulsing with their own rhythm. No sun, no surface — just creatures making their own light.
Click to spawn new orbs. Move near them to gently push them away. They drift, pulse, and slowly fade. Some find each other and orbit together.
Soft sine tones when orbs appear. A quiet drone in the deep frequencies. The space between sounds matters as much as the sounds themselves.
