I got 2 as well, but I also got frustrated when moving tiles didn't seem to register or something. I tried again, and it definitely seems like there are tiles out of place and I try to change them but they snap back sometimes.
In some cases moving one tile over another didn't work but it did work in the opposite direction. Definitely made the test a bit more difficult because it wasn't always obvious when a change had or hadn't worked.
Me as well. Funny thing is that with a non-calibrated monitor, I scored better than everyone in my art department including the art director... and I'm just a developer who knows a fringe level of Photoshop / Illustrator.
I scored 0 on a phone in quick time, and many other people here are reporting perfect scores as well. The fact that the scores of your art dpt are noticeably lower is thought-provoking.
Perfect score, but someone forgot to validate their inputs :P
