I've played most of the demo and I swear there are objects listed that aren't in the scene. I even used a hint which circled a non-existent object. If I exited the level and started it over, then the object I couldn't find was very obviously there. Seems buggy.
I really liked the first one in this series, so didn't play much of the demo of this one, but sadly as others have said, it glitches a lot. After paying extra for a collector's edition, this is unacceptable. First time I've had so much trouble with a Big Fish game.
I really like the other games in this series, but they have made changes to this one I didn't like. They took out the part where you buy souvenirs. They changed the playing field so now it is smaller. No more achievements. I hope if there is another installment, they go back to how it used to be.
