Theme interpretation is a 5 there were so many secret codes and one of them did this so now I can't find anymore. I liked the idea of looking around and solving puzzles to type the codes into the console, the only thing was the console took both the center screen input and your mouse input leading to typing in two letters at the same time. I'm not sure if the codes being typed in did anything, the only one I noticed was typing in 1337 because it blurred my screen.
