If this is the "updated" (edited down) Anuman version, this is one of the problems with following a walkthrough for the original -- the walkthrough will tell you do do things that don't exist in the edited version -- puzzles are partially or completely eliminated.
I doubt they'd chop off the part of the game where you see the white birds. They probably eliminated hotspots though, which can make it difficult to navigate or figure out where you are when you don't see anything that resembles the description in the walkthrough.
