Below the Root (1984)
Below the Root is an adventure game released in 1984 by Windham Classics, a division of Spinnaker Software. It is titled after Below the Root, the first of the Green Sky Trilogy of novels, written by Zilpha Keatley Snyder and published between 1975 and 1977. It is an early example of what later became known as the Metroidvania genre.
The player can assume the role of one of five characters with different abilities, a member of one of two races — the Kindar or the Erdling — and attempt to settle the existing differences between the two groups.
