The scatter distance is controlled by a few values: the force multiplier (800 / 200), the accumulation factor (0.3), and the max clamp (500). I'll scale all of these down to ~20% of their current values.
Reduced all three scatter distance controls to roughly 20% of their original values: the force multiplier from 800/200 to 160/40, and the max clamp from 500 to 100. The accumulation factor (0.3) stays the same since the force feeding into it is already scaled down. Letters will now scatter much more subtly while still following cursor inertia direction.
