The game is very faithful to Infocom's universe, down to the writing style and numerous references to Zork. There are dozens of puzzles that range from the very obscure to the ingenious. The parser is slightly disappointing – some obvious synonyms are left out, and some puzzles require you to use the exact syntax the designer has in mind. Still, the game quality overall is very good, and Zork fans will enjoy the off-the-wall humor and jokes. As a bonus, the game is much longer than an average freeware game, so you will possibly spend weeks on this warm nostalgic trip into the past. Unfair puzzles and obscure hints notwithstanding, Spiritwrak is a charming IF game and true to the spirit of Infocom's classics. Recommended!
