User Summary This game is the sixth in the Hi-Res Adventure series, and the first released under the SierraVenture line. The game is a tie-in with the Jim Henson film of the same name. In the game, the player controls Jen, the protagonist of the film, and the last survivor of a race of Gelflings, a mole-like people, as he attempts to find and repair the titular Dark Crystal, thereby restoring balance to his planet, Thra. Like Sierra Online's other graphical text adventure games, the player inputs simple commands in the text section of the screen, which are then carried out and represented graphically above.
