You...whip Hangry over to the the beheading machine (sorry, forgot the name for that thing) using the left arrow key (actually, you can use any key to do that). You then type in the word that appears on the screen after "set up" before the time runs out and watch the blood run haha...
Over and over again.
Okay, so you gotta do all of this as fast as you can because faster = more points. If you misspell a word (or when the time runs out), Angry loses a life.
