I'm at the part of the story where you play that cemetery minigame. It wants me to find 4 differences in two similar pictures and I only found 3 of them. I looked up Google and Youtube and can't find much content about the game or even a walkthrough guide. Appreciate the help I get from you guys.

This is a tough one. I don't have the game currently loaded, but what I did was make screen captures of both images, then used a graphics editor program to overlay one on top of the other.
