Headache? Hardly.
It's just a simple trial and error puzzle. They'll show you random **** from a video which you need to watch, which somehow clues into the tiny little puzzles. Just watch the video, write down everything that happens (so you don't have to watch that mind numbing trash again) and use it.
Seriously a waste of time. In a bad way.
I got one puzzle which had a bunch of gears you had to place to get certain preplaced gears spinning in a certain direction. I solved this in about 5 seconds, and it popped up and said, "What did he write about?" He would be the only man they flashed in the video, being Orson Wells. So I put in time travel, and it said correct answer.
What the ****? The process of getting the gears to work had nothing to do with the final question nor the final answer.
Call me when you get a real puzzle to solve.
