File:Doctor Zin's Underworld AMSTRAD CPC Longplay

Another excellent game by Hi-Tec based on a popular Hanna-Barbera cartoon character, Jonny Quest has you in the role of the schoolboy supersleuth as you roam the fortress of the evil Dr. Zin, rescuing your kidnapped comrades - your mystic Indian friend Hadji, your dog Bandit, your bodyguard, and finally, your inventor father. The game itself - a nice blend of platform action and Dizzy-style puzzles - is fairly big, but also quite linear, so you never get lost, and little surprises are thrown in along the way, like the enjoyable scuba-diving section, so you never get bored. The graphics are good and well animated, while the sound effects are sparse but serviceable. Also, the difficulty level is perfect; it's a challenging game, but not impossible.
