Easily one of the best GBA exclusive games. My second favorite in the series, the levels are generally short and sweet, with a decent mix of platforming and puzzles. Maybe someday I will do a hard mode play through.

One of the best GBA games I've ever played. Going for 100% is really fun. Each stage has its own music and feels unique. Controls are good. Definitely recommend this one, a must play.
