My first published work of Interactive Fiction. It got satisfyingly mixed reviews, and was nominated for the 2002 Xyzzy award for, of all things, Best Individual Puzzle.

Some quotes from reviewers -

• "...Constraints is a masterpiece, fearless and innovative...I'm quite literally running out of superlatives; this is perhaps the best thing I've seen anyone do with IF" (Mike Russo - a madman)
• "...few overt flaws...but equally without any real passion or originality... To me, IF on the topic of restriction with subject-matter reflected in form seems like painting about bad art by doing a really crappy painting...I am filled with an urge to propel the author's head through a plate-glass window. Or stained-glass, since it has big chunks of lead in..." (Sam Ashwell - a star)
• "...I really like it that the experience of playing made me think about such a philosophical issue in my own life...Constraints is quite exquisitely implemented...perhaps English isn't the author's first language..." (Paul O'Brien - who really cracked me up with that last bit)
• "...it's at turns boring, frustrating, annoying, or dull." (David Welbourn - getting straight to the point)

You could, of course, play it yourself. The story file - constraints.z5. See www.inform-fiction.org to find an interpreter for your machine (there will be one). Alternatively, you can play online an annotable version.
