Do I tap anywhere inside the arc?
Aim for the center marker. Landing inside the arc counts as a hit, but the leaderboard score uses exact millisecond error from the center.
What happens if I never tap?
The current-lap bar empties after one orbit and records a timeout. Standard continues; endless ends.
How does endless mode get harder?
Every successful arc hit reduces the orbit duration and target width. A tap beyond the target arc ends the run.
Does reduced-motion mode work?
Yes. The satellite must still change position for gameplay, but extra CSS transitions are removed when reduced motion is requested.
