## What is Stone Skip Go?

Stone Skip is a precision physics simulation built on a Spatial 3D lake environment.

PHYSICS ENGINE
- Dual-input control: independent power and angle sliders
- Sweet-spot mechanics: ~15-degree angle bonus coefficient for peak performance
- Per-stone skip coefficients: 5 stone types with distinct trajectory characteristics
- Random variance system: adds natural feel to each throw

VISUAL SYSTEM
- 2.5D Spatial 3D rendering: sky-to-water dual gradient with atmospheric depth
- Dynamic ripple animation: Circle stroke scale-expand with 1.2s fade simulation
- Moon glow and distant shore silhouettes for environmental depth
- StoneShape 3D pseudo-perspective: side face, top face, specular highlight

PROGRESSION
- 5 collectible stone types: Pebble, Slate, Granite, Jade, Obsidian
- Unlock thresholds: 4, 7, 10, 14 skips for each progressive unlock
- Historical data: last 30 throws stored as JSON via UserDefaults
- Real-time HUD: skip counter and power metrics during flight

PLATFORM
- iOS 17+ / iPhone only / portrait
- 100% offline: zero network, zero account, zero permissions
- Bilingual: English and Simplified Chinese
- Haptic: 3-tier feedback (light per skip, success, error)
