Product Principle:

By steadily rotating the generator crank, the current pen is able to move to the end of the track without touching it, successfully completing the challenge. If the pen accidentally touches the track midway, the alarm will sound and light up.

Gameplay Points:

Steadily rotate the generator crank with your right hand while holding the current pen with your left hand. Move the pen from the beginning to the end of the track, aiming to complete it in the shortest time possible with the fewest mistakes. The goal is to finish with the shortest time and lowest number of errors.
