## 1. Executive Summary & Core Game Concept

KeyFury replaces passive typing speed benchmarks with high-stakes 1v1 action fighting game combat. Instead of racing vehicle icons or looking at minimalist static graphs, two cybernetic warriors face off in a 3D battle arena.

- **Real-Time Input Execution**: Correct characters typed move the fighter into stance and initiate fluid attack animations in real-time.
- **Word Completion & Hits**: Completing target words launches combat strikes that physically impact the opponent, accompanied by screen shake, sparks, and audio synthesis.
- **200 HP Health Bar System**: Both fighters start with 200 Health Points (HP). Accurate words drain the opponent's health bar.
- **Round Duration**: Duels last 60 to 90 seconds. Rounds conclude via Knockout (KO) when a health bar reaches zero, or by highest remaining HP at time expiration.
- **Cross-Platform Device Support**: Engineered for both desktop (Windows, macOS, Linux, ChromeOS) with physical keyboards and mobile smartphones/tablets (Android, iOS) with on-screen virtual touch keyboards. No physical QWERTY keyboard is required to play on mobile.
- **100% Free WebGL**: Runs natively in desktop and mobile web browsers (Chrome, Edge, Firefox, Safari) with zero downloads or mandatory account setups. An installable Android APK is also available.

## 2. 3D WebGL Engine & Visual Architecture

KeyFury utilizes a dedicated 3D WebGL rendering pipeline built on Three.js:
- **Procedural PBR Materials & Dynamic Lighting**: Point lights, ambient glow, and bloom accentuate cybernetic armor and arena boundaries.
- **Cinematic Dynamic Camera**: Fluid camera angles track combat distance, zooming in during lethal combo finishers and sudden death climaxes.
- **Visual Feedback**: Real-time keystroke HUD highlighting (cyan for correct keystrokes, crimson for errors, gold for combo streaks) with particle sparks and impact effects.
- **Responsive Cross-Platform Input Pipeline**: Unified input handler supporting both physical desktop keyboard events and mobile virtual soft keyboard events, ensuring responsive typing feel on both desktop monitors and touchscreens.

## 5. Combat Mechanics & Health Rules

KeyFury features deep, deterministic server-authoritative combat mechanics:

### Starting Health & Damage System
- **Starting Health**: 200 HP per fighter.
- **Short Words (Jabs)**: Deal 2 base damage. Fast rhythm builders.
- **Medium Words (Kicks)**: Deal 3 base damage. Reliable mid-range strikes.
- **Long Words (Heavy Attacks)**: Deal 4 base damage. High-commitment power strikes.
- **Weapon Finishers**: Longest prompts deliver 6 base damage.

### Combo Overdrive Streaks
Maintaining consecutive error-free words unlocks escalating combat bonus tiers:
- **Tier 1 (3+ words - Power Strike)**: +1 Bonus Damage per word.
- **Tier 2 (5+ words - Weapon Finisher)**: +2 Bonus Damage per word.
- **Tier 3 (7+ words - Overdrive)**: +3 Bonus Damage per word (max combo bonus).

### Error Health Penalty
- **-2 HP Error Penalty**: Every typed mistake immediately deducts 2 HP from your own health bar. This mechanic penalizes mindless key-mashing and rewards composed, laser-accurate touch typing under pressure.
- **0ms Input Lockout**: No artificial input freezing. Typo recovery is instantaneous, allowing skilled typists to backspace and re-type with fluid cadence.

### Match Win Conditions
- **Knockout (KO)**: Draining the opponent's 200 HP before round time expires wins the duel instantly.
- **Decision at Time**: If time expires, the fighter holding the higher HP percentage is crowned the winner.
- **Sudden Death**: If HP is tied at timer expiry, a 15-second sudden death round begins with a 1-hit KO rule.

## 6. Competitive Matchmaking & Bot Fallback

- **Elo MMR Rating**: Wins and losses calculate Matchmaking Rating (MMR). Rank tiers include:
  - **Bronze**: 0 - 999 MMR
  - **Silver**: 1000 - 1399 MMR
  - **Gold**: 1400 - 1799 MMR
  - **Platinum**: 1800 - 2199 MMR
  - **Diamond**: 2200 - 2599 MMR
  - **Fury Master**: 2600+ MMR
- **5-Second Bot Fallback**: The matchmaking engine searches for real human opponents first. If no opponent matches within 5 seconds, an adaptive AI Bot Warrior (`Bot_Ronin`, `Bot_Valkyrie`, `Bot_Shinobi`, `Bot_Assassin`) is seamlessly injected. Bots simulate realistic human typing variance (40–120 WPM based on rank) with natural cadence and occasional errors, guaranteeing immediate queue fulfillment.
