Well i have just noticed this ^^:
While in the game menu (ICO or single player doesn´t matter) if i hold down the right mouse button i can turn the game view around, just like ingame.
I don´t know if this is intended or not as it really serves no purpose.
Also the view is not locked at top or bottom view, you can turn it over 360° in every direction, archieving some really weird scenes.
