The Book of Unwritten Tales is a game of high fantasy point-and-click puzzle-hijinks! Modding it was a puzzle too, but that puzzle has been solved.
This mod replaces Princess Ivodora Eleonora Clarissa's outfit with mostly a black texture. It also removes several unimportant lines of slightly tawdry dialogue, mostly Captain Nate's.
(I regret to say that the intro and ending movies still have the unmodified graphics, though, because I don't know how to fix that.)Modesty Go! (Nexus Mods)
