The update made it worse. It used to be good but now they require a longer ad in order to advance to the next image which takes less time than the ad to complete. There also used to be 10 differences, now there is only 5. Im going to look for a different game.

gameplay 5 star: great game for kids. But lost a star for technical and sound related issues: sound: most irritating, relentless and never changing millenial banjo whistle, and when turned off the sound effects are turned off as well :( When sound is turned off because you don't want sound, the ads still play at full volume. technical: you can't go back in levels (or at least not in an obvious way that I could find) so the lower levels you test before letting your child play the game, are gone.

Seems repetitive. Pictures are shown a few times and most, if not all of the differences are the same when they do repeat. On quite a few levels there's actually more things wrong than they allow to mark. Spotting the differences is easy and the levels don't seem to get harder the higher it goes like I expected it would. The pictures themselves are not of great quality. Pretty boring overall
