Nightmares from the Deep: The Cursed Heart Collector’s Edition Hints for iPhone/iPad
These scenes contain items listed in yellow lettering which require an extra step to find. A Mahjong game though can be substituted for the traditional hidden object scene.
It is always worth spending time moving the cursor around a scene and seeing if it changes into a hand, magnifying glass or gears.
There may be times when scenes will not progress, this may be caused by not having held a conversation with a certain character in that scene. If you are using the custom cursor, place it over a character to see if it turns to the lips icon. Most of the dialgos tend to be short.
