Portal

"Portal" is a innovative puzzle-platformer game where players solve puzzles by creating portals on surfaces to move between areas. The game is known for its witty dialogue, atmospheric setting, and challenging gameplay that requires creative thinking and problem-solving skills. Players control Chell, a test subject in the Aperture Science facility, and must navigate through a series of test chambers while being guided by GLaDOS, an artificial intelligence with a dry sense of humor.
