Secret Agent (sometimes called Secret Agent Man or SAM) is based on the Crystal Caves engine, with the addition of an overhead map to move between levels. Although Secret Agent was released after Crystal Caves and has a slightly more advanced engine, development actually started earlier and so technically Crystal Caves is based on an early version of the Secret Agent engine.
