Dino Desert Runner is ready! Here's what's in the game:

- **Pixel-art dinosaur** auto-runs through a scrolling desert landscape
- **Jump** with Space/W/Up Arrow or tap on mobile to dodge cacti (big saguaros + small barrel cacti)
- **Speed increases** gradually over time making it harder to survive
- **Score** ticks up every 100ms; every 100 points earns a coin + screen flash
- **High score** saved locally + submitted to leaderboard
- **8-bit chiptune soundtrack** with retro jump/hit/point SFX
- Parallax scrolling desert background + tiled ground

**Next Ideas:**
1. **Flying Pterodactyl Enemies** - Add aerial obstacles at random heights that require ducking (crouch mechanic) or precise jump timing
2. **Night/Day Cycle** - Gradually shift the sky color palette as score increases, with stars appearing at night and different obstacle variants per time of day
