I mean, all it is is gathering clues to put together an answer. To me it seems rather simple. Though y'know, someone viewing the puzzle for the first time, they might be stumped.
Of course there's the guy who got one of the clues, though there are a few more before you can actually see where the answer is coming from.
I didn't put Tooooo much effort in, just like, 7 or 8 hours of coming up with clues that made reasonable sense, then giving an overall look of it which didn't give too much away
