The Radiant Orchard Comprehensive Product Requirements Document & Technical Master Specification Document Version 2.1.0 (Detailed Roadmap Edition) Target Platforms Mobile (Android & iOS) Core Engine Stack Unity 6 + Flutter Embedding via flutter_unity_widget 1. Executive Summary & Core Concept The Radiant Orchard is a tactile, fast-paced 3D mobile diorama game designed to teach nine moral virtues through intuitive touch gesture mechanics and biological health metaphors. Set on a tranquil, Tiny Glade-inspired floating island, players step into the role of the Caretaker. The game begins on an entirely grey, desaturated, and quiet floating rock featuring only two permanent landmarks: an ancient Stone Well and a grand Wisdom Tree. Players interact with the world by planting virtue-fruit trees, listening to the needs of visiting characters (Stickmen), and delivering healing tonics. Restoring these characters brings vivid pastel colors back to the island, gradually transforming a lonely grey stone into a thriving, colorful, and vibrant paradise. 2. Complete User Journey & Game Flow Phase 1: Launching the Game & The Empty Island • The Starting Atmosphere: When opening the game for the first time, users are greeted by soothing lo-fi background music and an isometric view of a floating island. • The Environment: The terrain is completely grey, desaturated, and devoid of color. Only the mossy Stone Well and the Wisdom Tree stand tall. • The Well Wish Feature: Before starting, players can interact with the stone well by dropping a coin to make a personal wish, establishing an immediate emotional tie to the world. Phase 2: The First Visitor & The Guided Introduction • The First Arrival: A slow-moving, completely desaturated Stickman walks onto the island path. • The Symptom Bubble: A 3D thought bubble appears overhead, showing a visual symbol of fatigue or emotional distress. Confidential — Client Deliverable Page 1 THE RADIANT ORCHARD Product Requirements Document · v2.1.0 • The Gentle Guide: A friendly, non-intrusive on-screen guide pops up to help the user: “Our first visitor needs help. Let's plant our very first tree to gather what they need.” • The First Action: The user taps a designated spot to plant a tree, learns how to harvest the fruit using a simple touch gesture, and watches it transform into a glowing tonic that heals the visitor. Phase 3: The Core Gameplay Loop Once the introduction concludes, every level follows a repeating, engaging 4-step cycle: • The Request: Grey, low-poly Stickmen spawn on the island displaying symptom-based thought bubbles. • The Harvest: The player performs precise touch gestures on the screen to harvest the required fruit from the orchard. • The Delivery: The harvested fruit instantly transforms into a 3D Vital Tonic bottle that flies in a smooth arc trajectory straight to the requesting Stickman. • The Transformation: Upon receiving the tonic, a color shader sweeps across the character, restoring full pastel colors, executing a joyful celebration animation, and raising the island's global Vibrancy Meter. Phase 4: Progressive Difficulty & Island Expansion • Level 1 (Relaxed & Easy): Slow pacing, generous patience timers, and simple requests so the player can comfortably learn the mechanics. • Mid & Late Levels (The Challenge): As players advance, multiple visitors arrive simultaneously, patience timers drop faster, and managing multiple tree types requires strategic quick thinking. Phase 5: The Wisdom Tree Micro-Quizzes (Every 5 Levels) • The Pause Event: After completing every 5 levels, standard gameplay pauses for a rewarding break. • The Scenario: A clean bottom-sheet UI overlay slides up displaying a situational scenario (“A friend is feeling restless and anxious. What fruit do they need?”). • The Reward: Selecting the correct answer (Watermelon / Peace) triggers Golden Harvest Mode, doubling earned points and bathing the island in a warm, glowing particle filter for a limited time.
