This GBA game brings together two Scooby-Doo adventures. The specifics of gameplay are unclear without knowing the exact content of each game, but it's safe to assume puzzle-solving and adventure elements. Given the 'Independent' label, the titles are probably simplified versions of the original games, focusing on basic adventure gameplay.
