Quote was originally a concept for Hard made by some random dude (also the original source for "Ice in the Freezer" and "Clouds in the Sky" before the video "Fire in the Hole: New Versions" came out) and difficulty by Wolfcube, and it was added in version 3 if memory serves me right (it added all the emoji difficulties like Embarrassed, Silly, Disgusted, Surprised, Concerned, and Uncertain)
