In the video, a person is holding a smartphone in their hands and playing a game on it. The game appears to be a simple one, with a small green character that the person controls by tapping on the screen. The gameplay involves the character moving around a room, collecting items, and avoiding obstacles. The person successfully completes the level, and the game displays a congratulatory message with three stars and a score. The person then taps on the screen to replay the level.
