About Halcyon
Halcyon is an adventure game where you explore a tropical atoll throughout a single day. You begin at sunrise and navigate the environment by walking across the sand, swimming through the lagoon, and sailing past the reef to observe whales. As the day progresses, you can stay until the sea begins to glow with bioluminescence. The controls are straightforward, using WASD keys to move your character and clicking and dragging to look around the surroundings. The goal is to experience the changing atmosphere of the island from morning until night.
This experience stands out for its focus on atmosphere and exploration within a scanned environment. It is well-suited for players who enjoy relaxing, self-paced discovery rather than high-stakes challenges. Sessions are short and meditative, making it a perfect choice for a quick break. The game was built using Claude Code and Three.js, and it is designed to be played in a web browser.
