Pattern Difference

This was a tough one! I’m not gonna lie to you because I like you but I really had to look and look and look again to find all the differences in each level. Every time I found a difference, I clicked on it with my mouse (you can click on either image) but it was hard to find them all in under four minutes. The hints helped but they only showed up for a second and they cost thirty precious seconds. I gave up before I completed all the levels, but I bet you’ll have no trouble at all!
