I'm not sure how I got it, but I got it? Then I went back and tried the same person again and it said incorrect? I'm not sure what I was looking for or why I was looking for it.
The is a cool concept, but I think the perspective/depth of the photos with the pixel art made it pretty difficult to figure out what I should be looking for. I'm not sure what could be done about it though. More clarity? Maybe even a tutorial set to teach the player how the game works. For example, are the pictures chronological? Do the go left to right or right to left?
Still a really cool experience to have made in a weekend. The music works really well and the images are cool by themselves. Well done and congrats!
