I have never seen Being John Malkovich, but this game is loosely based on it. In this game, you gain access to Andrew Plotkin (a.k.a. Zarf), author of games such as Shade, So Far, Spider and Web, and a million others. You play several characters, including Zarf and a couple of young lovebirds.
The game is relatively short, taking less than an hour. The humor is mostly absurd humor, with numerous references to Zarf's fiction. I had only played a few games at the time; it is probably worth it to work through a lot of Plotkin's games (like So Far and A Change in the Weather) before playing this game, or afterwards. Unfortunately, these games are extremely hard, so if you're not a puzzle fiend, consider a walkthrough.
Great writing, mostly good puzzles, and a fun setting. I recommend it for everyone.
