Based on the movie and book series, Lemony Snicket's A Series of Unfortunate Events for GBA is a puzzle-platformer that follows the Baudelaire orphans—Violet, Klaus, and Sunny. Players must switch between the three siblings to utilize their unique talents: Violet invents gadgets, Klaus uses his intellect to decipher clues, and Sunny uses her sharp teeth to bite through obstacles. The trio must outsmart the evil Count Olaf, who is after their inheritance, by solving environmental puzzles and collecting items to build inventions. The game faithfully recreates the gloomy, gothic atmosphere of the series and offers a cerebral adventure similar to 'The Lost Vikings'.
