Gris et Jaune was the first IFComp 2010 game I played, due to the writeup over at JayisGames.com. In effect, they said: "We'd hate to spoil even the beginning for you. Just play."
So I did. And I think you'll enjoy it best that way, too, so I'll keep my comments brief.

The beginning grabbed me in a way that I haven't experienced since parts of ANCHORHEAD.
I've never seen this setting before in IF. It begs the question: why hasn't someone set a piece here before?
There's a lot going on emotionally. More than you'd expect from a work featuring (Spoiler - click to show)a zombie.
That said, I'm not sure how much of that emotion was conveyed clearly. I had a lot of questions about a certain character (Spoiler - click to show)--Mama John-- and how things fit together between some characters. (After emailing the author--whom I found very congenial--about it, it sounds like we may see some changes in the post-comp edition; hopefully the emotional links will become more clear.)

Gris et Jaune isn't perfect. But there is something very special about it. Play it. You'll feel the heart that went into it.
