The chap who created Passage has another weird game about moods and those other afflictions suffered by human beings. It's called Gravitation, and has a similar flavour to the melancholy game of life we wrote about last year. Created Jason Rohrer calls it "a video game about mania, melancholia, and the creative process." I don't think it quite has the impact of Passage, although it's not without some poignant ideas. I suggest you see what your own "reading" of this one is.
