In this underrated action adventure, you are baby-faced Digger T. Rock, exploring underground caverns in search of the Lost City. The goal in each cavern is to find the exit while collecting jewels and equipment like dynamite and ladders. While the game excels at providing the sensation of exploration, with Digger climbing, spelunking, jumping and digging through simple but well-defined environments, it falls short in the action department. It's too easy to get hit by the cavern's creatures, especially while crawling through passageways.
