The battle physics have been significantly improved:

1. **Wider starting positions** - Beyblades now start further apart (0.5 * arenaRadius vs 0.05)
2. **Higher launch speed** - 800 base speed (up from 600)
3. **Lower friction** - 0.85 retention per second (vs 0.6), so they move faster longer
4. **Stronger wandering** - 400 strength (up from 150) with faster oscillation
5. **Stronger attraction** - 350 (up from 250) so they seek each other more aggressively
6. **Higher target speed** - 280 minimum maintained speed (up from 180)
7. **Bigger knockback** - 1.2x multiplier (up from 0.8x) and max bounce 400 (up from 250)
8. **Better wall bounces** - Minimum 200 speed after wall hit (up from 150)

The beyblades will now move much more dynamically around the arena!
