There's a Quest game "Gathered In Darkness" by Dr. Froth in this year's IFComp.
You can download it from
this page.
Alternatively, you might find it quicker (as I did) to just download the entire games package from a mirror:
http://www.ifcomp.org/comp07/download.htmlThe rule on discussing competition entries has been
relaxed this year, so we're free to discuss the game here. And any of the other games of course - even though they're not written in Quest, I do really recommend you try them out, just to give you an idea for what other people are doing with text adventure games.
