It's a cute and short game. It clearly tries to pad its length with the maze everyone complains about (I agree you should just look up the path to take, there is no hint in game as to what to do). If you like the novel and want a silly follow-up, it'll only take 2 hours of your time.
The game only took me an hour and a half to beat! The puzzles were logical for this kind of game and doesn't have the nonsense of secret files 2. The main character is annoying, but the plot is the start of a fine adventure game. It goes nowhere though. You just kind of do a lot of reading to get the plot and can easily ignore it. I just wish there was more. It's amusing enough if you can get it for a $1.
