Transformed the game into a 3D POV bike ride through city streets. Here's what's new:

- **First-person POV** riding a bike down a multi-lane road
- **Traffic cars** (red & blue 3D models) coming at you in both directions
- **City environment** with buildings, sidewalks, trees, road markings, and a yellow center line
- **Dodge cars** by steering left/right (A/D or arrow keys), bunny hop with Space to jump over them
- **Coins** float above the road to collect for bonus points
- **Head bob & sway** camera effects for immersive riding feel
- **Car horns** honk randomly, wind rushes louder as you speed up
- **Progressive difficulty** - speed increases over distance, cars spawn more frequently

**Next Ideas:**
1. **Night Mode** - Add a day/night cycle with headlights on cars, street lamps glowing, and neon building signs
2. **Power-ups** - Spawn speed boosts, shields, and coin magnets on the road for pickup
