Lots of guessing to find the right solution on the face. A good puzzle given the complexity of the subject, but not for someone who prefers to use logic than guessing.
Eh, I just wanted to make the Annoying Dog. Sure, the face is a bit of a pain, but anyone who gets the reference would be able to get it quickly. Anyways, I'll try not to have guessing in future puzzles.
I kind of agree, a lot of people probably wont get the reference, since this isn't really a gaming community site. Heck, I play the game and I had to look up the image online to get the face. However, still a cute puzzle.
