Blinking orbs. Better adaptive difficulty

Orbs now blink to indicate their state. When you chase them, they blink faster to indicate they're stressed and trying harder to escape. Some times a gentler and quieter approach is best.

Much wider range of difficulty. At minimum difficulty, orbs will just be captured where they are without escaping.

New shader for the rings. Includes shine and shimmer for more variety

Less tiles in planet surface to reduce generation times.
