First, there were glitches. There are groups of 3 photos in each level. I’d find all 3 differences in each photo of a level, but the game would still only give me credit for passing 1 or 2 photos. Plus, I didn’t like that many of the photos sexualized women. There’d be a bunch of photos with food, architecture, or nature scenes. Then there’d be one with a woman in a TINY skirt posing in a provocative manner! There were only 4 men even included in the photos, but dozens of “schoolgirl” photos. Finally, I did over 100 of these, and they never got harder. For every one, there were only 3 differences per photo. I just deleted after playing for only a couple of hours.
