When can I select the balls?
Selection begins only after every ball stops. A countdown bar appears and the balls become clickable.
Can moving balls overlap or cross?
Yes. Their paths can cross, which makes continuously following the targets more important than remembering one area.
What changes in later rounds?
The game increases target count, movement speed, and the number of distractor balls.
Does reduced-motion preference work?
Yes. Reduced-motion mode shortens and slows the movement phase while preserving the tracking task.
