I first came into contact with Sand-dancer through Aaron's book "Creating Interactive Fiction with Inform 7". But I decided that I wanted to try the game before creating it myself. And I'm really happy that I did, the game or perhaps we should call it story takes place in the desert or perhaps in the mind of Knock the main protagonist as he's stuck in the desert and a storm is coming.
The story and the mood is what really shines in this short story and the different possible choices actually calls for a few play-throughs.
I really enjoyed this little gem and I can heartily recommend it.
