My problems seem to be basic. In Kings Quest 8 - Mask of Daventry, I have saved several games, but I do not seem to know how to restore one. I am sure it is in the book that came with the game, but I don't seem to be able to find it or understand it if I did.

I think this is how I did it.

Press Esc to get up a menu, then press down-arrow (on keyboard) to load
and press enter. There you can highlight the game you will restore and either choose load or enter again. Good luck.
