## 1. What is BodyRush 3D?

**BodyRush 3D** is an arcade fitness, rhythm boxing, and posture-wall runner game for **iPhone** and **iPad** (with native **16:9 AirPlay TV** support). Players place their iPhone or iPad 2 meters (6–8 feet) away on a table, TV stand, or tripod. Using Apple's on-device **Vision framework** at 60 FPS, the front camera tracks **19 human body joints** in real time with zero controllers, zero wearable sensors, and zero VR headset.

### Key Differentiators
- **100% Camera-Controlled Full-Body Gameplay**: Run in place, dodge across 3 lanes, jump over low barriers, squat under overhead beams, punch monsters and rhythm cubes with left/right/double fists or front kicks, and match 10 full-body neon posture silhouettes.
- **Beat-Quantized Musical Difficulty Scaling**: Higher difficulties multiply **musical event density and chained combo complexity** synced to the song's BPM and real-time bass drops (`~40` obstacles in EASY, `~80` + x2 Combos in NORMAL, `~125` + x2/x3 Combos in HARD, `~175` + x3 Combo flurries in EXPERT+).
- **Explicit Movement Rules (No-Jump / No-Squat Options) & Unlimited-Hearts FIT Modes**: Every level explicitly displays whether it excludes jumps (`🚫 Sans Saut` — apartment/neighbor-friendly), excludes squats (`🚫 Sans Squat` — knee-friendly), or includes all movements (`✅ Tous les Mouvements`). Levels 05–07 (`5 MIN`) and 08–09 (`10 MIN`) feature **Unlimited Hearts (`♾️`)** so players never get a Game Over during their timed cardio workout, culminating in **Level 09: 10-Min 6-World Megamix Bonus**!
- **True 16:9 AirPlay TV + Low-Power Skeleton Cockpit**: When mirrored or connected via AirPlay to a television, the TV displays a dedicated 16:9 widescreen 3D view while the iPhone/iPad switches to a lightweight Skeleton Cockpit HUD to prevent thermal throttling.
- **Living-Room Pass & Play Tournament (2 to 4 Players)**: Friends and family take turns in front of the camera on the same world and track, culminating in a **3D Photo Podium** with automatic action souvenir photos and shareable finish video replays.
- **100% On-Device Privacy**: All camera frames are processed in RAM by the Apple Neural Engine and discarded immediately. No video or biometric data ever leaves the device. Works completely offline (even in Airplane Mode).

## 2. Detailed Gameplay Mechanics

### 2.1 Forward Locomotion & Turbo Run
- **Running in Place**: Alternating knee lifts / stepping in place drives the player forward through the 3D corridor. If the player stops moving, the corridor decelerates.
- **🔥 TURBO RUN Mode**: Triggered only when the player performs an all-out full-body sprint — pumping **both arms and both legs rapidly at the same time** (sustained high joint velocity above threshold for >0.55s). Turbo Run boosts corridor speed by **+50%**, triples distance score (**x3**), widens camera FOV, and ignites comic-book speed flames around the HUD.
- **⚡ Posture Auto-Glide**: Holding a target posture at **≥ 52% accuracy** as a Neon Posture Gate approaches automatically propels the player through the gate without needing to run in place at the same time.

### 2.2 The 4 Action Families
1. **Boxing & Combat (`Niveaux 01, 05, 04, 08`)**:
   - **Left Punch / Right Punch**: Punch left-lane or right-lane villains and directional rhythm cubes.
   - **Double-Hand Smash**: Punch with both fists simultaneously to shatter center bosses and reinforced obstacles.
   - **Super Kick**: Front foot kick detected by ankle/knee elevation to smash crystal walls and villains with bonus points.
   - **Brittle Cracked Crystal Walls**: Translucent fractured walls broken with a single clean punch.
2. **10 Camera-Tracked Posture Gates (`Niveaux 02, 07, 04, 08`)**:
   - **EASY (4 Poses)**: `T-Pose`, `Hands Up (Bras Levés)`, `Boxing Guard (Garde Boxe)`, `Star Jump (Étoile)`.
   - **NORMAL (7 Poses)**: Adds `Double Biceps Flex`, `Victory V`, `Overhead Diamond`.
   - **HARD & EXPERT+ (All 10 Poses)**: Adds `Super Hero (Fists on Hips)`, `Flamingo Balance (One-Leg Stand)`, `Zen Warrior (Wide Sumo Stance + Open Arms)`.
   - Passing a posture gate triggers an automatic **Action Souvenir Photo** framed with the player's score and morphology stats.
3. **3-Lane Dodging, Squats, Jumps & 3D Stairs (`Niveaux 03, 06, 04, 08`)**:
   - **3-Lane Lateral Dodge**: Step left, center, or right in your living room to avoid vertical pillars and rolling boulders.
   - **Deep Squat (`↓ BAISSE-TOI`)**: Bend knees and lower hips/shoulders to duck under overhead beams, lasers, and ceiling spikes.
   - **Real Jump (`↑ SAUTE`)**: Jump with both feet off the floor to clear low hurdles or climb multi-floor 3D stairs (`Étage +1`, `+2`, `+3`).
