Ben 10 Car Differences

You control a cursor, clicking on discrepancies between two nearly identical side-by-side images. Your main goal is to find all the differences before the timer runs out. The game gives you a two-minute limit to work through a set of ten pictures, and you can only make a handful of mistakes before failing. You could disable the timer for a more relaxed pace, which was helpful for younger players. The difficulty comes from the subtle changes and the pressure of the clock. It feels like a focused, sometimes frantic, test of observation.
