Sorry, not exactly. Some PDF viewers allow you to rotate pages. If yours does, you could rotate the 2nd page so it is easier to read.
What kind of screen-friendly format were you thinking?
well, if you placed all of the "pages" upright as singles or spreads that would work wonders. if I turn the book around by 90 degrees, the 1st page will be half upright, half upside down. that's pretty hard to use on a pdf reader because one will be turning the pages every few moments to use the game. I don't own a printer so this shape is immediately difficult to use.
