And there are a few I haven't played yet, like the highly-rated Time Gentleman, Please!, Nancy Drew: Ransom of the Seven Ships, Drawn: The Painted Tower, and Wallace & Gromit: Fright of the Bumblebees.
Rosemary was a project led by Clara Fernández-Vara, drawing on her Ph.D thesis work on adventure games and the Tools for the Telling project with Nick Montfort and Alex Mitchell.
