Rhem

Rhem is a first-person, point and click adventure that can be compared to Riven. You ride into the large, unusual world of Rhem in a mining cart and soon you discover that you are unable to leave. Your major objective is to find a way to leave Rhem. To do this you must find and reconstruct a letter which has been divided into four parts and hidden. You will do this totally alone without interaction with any other characters.

Many of the areas are closed to you at first and the way to open them is by solving a multitude of adventure-type puzzles. There are mechanically based puzzles involving levers and switches, but you will also find codes to decipher and strange symbols, maps, color patterns and switchboxes.
