クエストとロケーション選択メニューを備えた一人称オープンワールド冒険

Build a first-person open-world adventure game with a story. Create a large landscape of grassy hills, dry red plains, a sandy beach and sea, dotted with trees and strange landmarks such as a glass cathedral and an orchard. The player carries a white pistol. Add a quest log and objective markers, narrated dialogue shown as subtitles, and a calm muted HUD with a compass strip and location titles that appear when entering an area. Include a menu titled like a world-jump screen that lists named locations as cards so the player can teleport between them. Use soft daylight, a restrained teal and green palette and clean thin UI typography. Deliver it as one runnable project with WASD movement, mouse look and click to fire. Done means the player can pick a location, explore, trigger dialogue and complete an objective.
