Both the regular (99 cents) and HD versions ($1.99) are on sale this weekend. I'm tempted to get the HD version as I like the other Alawar titles, though this one has had some mixed reviews.
I had Natalie Brooks 2 from this dev house and I enjoyed it very much...so I grabbed Joan Jade and I'm having fun with it ye...many variety in this game: there are puzzles to solve (i.e.: put a stone in the hands of a statue), mini-games and hidden objects scenes...it's a steal at this price! edit: I have iphone version (99 cent)
