The Immortal, an adventure game (RPG) released in 1990 by Electronic Arts. The first version of the game was released for Macintosh, later moved to Amiga, Atari ST and PC and NES consoles.
In the game we play a wizard (not named a frog), whose purpose is to rescue (find) a mentor (magician gurus) named Mordamir. The road to Mordamir is a multi-level maze in which you will face many dangers (eg goblins and trolls) and a number of puzzles to solve. During the game you will be able to join an alliance with goblins or trolls.
The Immortal is a game of horror and violence scenes (NES version is devoid of blood), only for players with strong nerves (or Diablo fans).
