Inspector Gadget: Advance Mission stands out on the Game Boy Advance as a surprisingly faithful adaptation of the classic animated series, leveraging the handheld’s 16-bit power to deliver vibrant, cartoonish visuals. What makes this version special is its character-swapping mechanic; players can alternate between Inspector Gadget, Penny, and Brain, each possessing distinct abilities necessary to navigate the levels. Gadget utilizes his signature bionic tools, Penny employs her computer book for puzzle-solving, and Brain provides agile platforming. This multi-character approach adds a layer of depth often missing from standard licensed platformers of the era. For collectors and fans of retro handhelds, this title is a noteworthy example of early GBA development by Magic Pockets. It captures the charm of the IP while offering varied gameplay loops, making it an essential addition for those seeking to complete their library of animated adaptations or classic portable action games.
