Starfish Reef Foraging Lab (2D)

A top-down companion to the 3D reef scene: starfish steer toward chemical scent markers scattered across the reef floor, spend energy skirting rocks, and refuel whenever they arrive.

This 2D companion drives the same "forage" mechanic as the 3D original from a plain top-down view: starfish steer toward the nearest active scent marker, a wander term shrinks as chemoreception rises, and reef complexity controls both how many rocks they must skirt and how fast they burn energy doing it.

⚙ Under the hood

Canvas2D steering-behaviour lab: population, reef complexity and chemoreception sliders drive starfish foraging toward glowing scent markers, with an energy budget that depletes on rugged terrain and refills on contact.
