I know, the face tracking isn't great yet, but it's hard to make it without [if touching color] blocks! Those don't work with the camera. Basically, I only used the: [Camera Motion On This Sprite] block, by positioning a bunch of square clones all over the stage. They figure out which is the highest of them that has movement on it, and that is set as the y of the top of your head. If you stick your foot above your head and wiggle it without pulling a muscle, the hat'll follow. Hold shift and 1 to show the squares.
WIP! This is not the final version. Press space to change the hat and glasses. I know that its bad right now, but it will be better later!
