《99 Nights as a Frog》产品需求文档 (PRD)

1. 游戏概述 (Game Overview)

• 游戏名称: 99 Nights as a Frog
• 元描述: Survive ze nights as a frog
• 屏幕方向: 横屏 (Landscape)
• 适配平台: PC网页端 / H5移动端

2. 核心功能与系统设计 (Core Features & Design)

以下是根据 AI 对话创作历史整理的核心系统模块：

• 核心机制: Fixed the message system to check for duplicates against every message in the queue, not just the top one! Now any matching message will get the pulsating effect and timer reset. 🎯
• 核心机制: Added a "Show Player Position" checkbox to the game settings! You can now toggle the coordinate display at the bottom of the screen on or off. 📍
• 核心机制: The minimap is now hidden but still exists in the code - you can easily bring it back later when needed! 🗺️
• 核心机制: Added a terrifying deer enemy that stalks you at night! This horror creature walks upright, has long pointy fingers, glowing white eyes, and only appears when you're far from the safety of your campfire. It moves slowly but deals heavy damage - stay alert! 🦌👹
• 核心机制: The deer now appears twice as large visually while keeping the same collision size for combat - making it even more intimidating when it stalks you! 🦌👹
• 核心机制: Perfect! I've added a vertical offset to move the deer artwork up by 40 pixels so its feet align with the shadow, and spawned a test deer near the campfire so you can see it immediately and iterate faster! 🦌
• 核心机制: The deer's artwork is now 20% smaller while keeping the same collision size - it should look more proportional while maintaining the same gameplay mechanics! 🦌
• 核心机制: Perfect! The deer now has smart day/night behavior - during the day it flees from the campfire, but at night it becomes a terrifying stalker. Only one deer will ever exist at a time, making encounters more intense! 🦌🌙
• 核心机制: The campfire is now a safe zone from the terrifying deer! When the fire is lit, the deer won't get close and will circle around menacingly instead. I've also doubled its chase speed at night - much more intense stalking! 🔥🦌
• 核心机制: Fixed the deer's flickering behavior! Now when the deer is within the campfire's safe zone and you're also in the safe zone with the fire lit, it will simply stop moving instead of constantly switching directions. The deer will stay put until conditions change, eliminating the jittery back-and-forth movement. 🦌🔥
