SPAM THE FLAG!!!!!! It uses the Face Sensing extension to scan your face, and see if you are the same person! — Move your head up, down, left, and right. (Not too slow, but not too fast) Keep it in the view of the camera. Is it taking a long time? Look at the bottom of the screen to see how much longer you have left! Takes approximately 15-30 seconds. Don't rush it!
Thanks to @griffpatch for his color scanning tutorial!!
