This is a copy-protected image of the Comprehend engine re-release of Transylvania. The copy protection detects that this is not an original disk and renders one room in the game inaccessible, making it impossible to win. (SPOILER: If you enter "north, west, north, east, pull horns" on the first move, and the resulting text ends in "It wobbles," the copy protection is active and the game cannot be finished.)
