Pitfall: The Lost Expedition on the Game Boy Advance is a fun throwback to classic platformers, with plenty of vine-swinging and pit-hopping action. The varied environments, ranging from jungles to ice caves, keep the gameplay fresh, and the humorous dialogue adds a lighthearted touch. While the camera can be frustrating at times and the difficulty spikes unexpectedly, it's still an enjoyable adventure for fans of the genre.
