Avelin Rayo

Step into the dark. Avelin Rayo is a creature-collection game built around the hidden world of bioluminescence. Every species starts as a silhouette drifting in shadow — unknown and unlit. Learn its signal, perform the right gesture, and watch it flare into color right before your eyes. The creatures respond to touch. Some answer to rapid pulses, others to a slow sweep across the screen, and some only emerge when you hold completely still. Every glower has its own stimulus, its own timing, and its own color — amber, cyan, teal, violet, and green lighting up the dark as you master each one. Explore four distinct biomes — the warm coral Reef, the near-black Abyss, the cold Cave, and the mossy Forest Floor. Each environment shelters its own cast of real bioluminescent species, from the anglerfish and vampire squid to the foxfire mushroom and railroad worm. Rare and legendary creatures hide behind the most precise signals; fill every biome to complete your collection. Every capture adds a scientifically grounded species with a real biological fact. Avelin Rayo rewards patience, pattern recognition, and the quiet thrill of coaxing living light from the dark. Start with a black tank. End with a glowing world.
