Some highlights from the manual......
You can turn left, right; look down, turn and look down or up.
In the bottom left corner of the screen is an icon telling you which way you can turn and/or look.
In the inventory (below main screen) an item is activated automatically after the place where it can be used is indicated on screen. You don't have to test everything in inventory to know what to use.
You can save when you see a flag on the map in the bottom right corner of the screen. Cannot save at puzzles.
Just some of the manual info.
P.S.......Although saves are limited to 16, you can (if you know how) save all you want in groups of 16 or less.
