I downloaded this app a few months ago, since me and my mom love these kinds of games. We were doing good and liking the app; it wasn’t too easy nor too difficult. However, starting from level 249, the game must have a bug or something, because then the “correct” answers are just random. Me and my mom find all the actual differences, but the game says they aren’t correct and when we use a hint, it shows us the “answer” in a place where there is no difference at all. Plus, the hints are 30 seconds long. Me and my mom know that we are correct because we have checked with multiple other people. This was a great game, but because of levels 249 and up, we cant play it now. It’s a pity.
