枯れ木と生き物がいる霧のサードパーソン・オープンワールド

Build a third-person 3D open-world game that runs in the browser. The world is a barren, misty wasteland with dry brown ground, leafless dead trees, scattered rocks and small plants, soft volumetric fog and a muted teal-and-amber palette. A small avatar is controlled from an overhead chase camera, can walk around, use a glowing ring marker on the ground and interact with creatures such as a purple mount that appears nearby. Include name tags above characters, a compact chat or quest log panel in a corner and small interface icons along the top edge. Add subtle ambient motion: drifting fog, swaying grass, dust puffs when moving. Controls are click or keyboard movement plus an interact key. Done when the player can explore the foggy terrain, see other characters with name tags and interact with at least one creature, with a stable frame rate.
