What is "rhem"

RHEM is an adventure game from Knut Müller and Got Game Entertainment. It is distributed as a Macromedia Director file. The player explores a barren, maze-like landscape of water ponds, walkways, and brick buildings with the aid of a partial map. The game has several puzzles involving machines and symbols. There are three sequels, called RHEM 2: The Cave, RHEM 3: The Secret Library and RHEM 4: The Golden Fragments.

RHEM, like Myst, is made up of a series of static images.

The object of the game is to locate four pieces of a letter, which must be pieced together.
