I just finished playing Gorogoa for a second time and it is wonderful. It's clever, beautiful, and absolutely unique. (There haven't been many truly unique adventure games since MYST in 1993.) I do have a couple questions about it. First, was it successful enough for the developers to consider a sequel? Also, the game has a title page that labels the game "Buried Signal." What does that title have to do with anything? Whatever the answers, the game is great fun.
