Pyramid was one of Aardvark Technical Services's (later Aardvark-80) first Coco adventure games (at this time they also did games for the Commodore PET and TRS-80 Model I/III) and was written in BASIC. They labelled this one as being their "most advanced and most challenging adventure". It takes place inside of a Pyramid and the goal is to get all of the treasures.
