The higher the level, the easier it is to find mistakes⁉️

This is a spot-the-difference game I'm playing on another point-earning site. You have to find 15-25 differences between the top and bottom pictures. Not all the differences are there from the start; there are a few initially, and as you find them, parts of the picture change, revealing more differences to find. I'm over level 1000 now, and ever since passing level 900, I can often clear stages without any hints.
