Windhaven coastal fantasy adventure

Design a game with me. The game should be built in Unity. Use default asset first and I will replace assets later. Game style: A premium stylized coastal fantasy adventure game set in a small sunlit island city called Windhaven. The city is built from warm ivory limestone and golden sandstone, surrounded by clear turquoise water, with teal copper roofs, shaded market stalls, arched gateways, lush courtyard trees, carved fountains, glowing magical beacons, and a monumental temple overlooking the town. A lone young explorer wearing a travel cloak and backpack walks through the central plaza toward the temple. The environment feels peaceful, mysterious, ancient, and gently magical, with Mediterranean and North African architectural influences. High-detail stylized PBR materials, handcrafted stone surfaces, subtle weathering, elegant decorative carvings, soft afternoon sunlight, long cinematic shadows, turquoise and warm gold color palette, polished AA adventure game art direction, third-person gameplay camera, wide establishing shot, cohesive environment design, visually readable paths and landmarks, no UI, no text, no logos, no modern objects.
