The Barrier
The game is based on the “10-second barrier“, which is “a term used in track and field athletics, which refers to the physical and psychological barrier of completing 100 metres sprint in under ten seconds.”.
In this case you have to run 100 meters in exactly 10 seconds. And you are an alien!
