*Spoiler* Instructions for "The Machine." To beat "The Machine" you need to keep from getting your arm cut off for 30 seconds. The buttons on the left and right each have an arrow that shows which way the saw blade will move if you tap the button. After a certain amount of time the green button flashes. Sometimes it will flash and say "reverse polarity" which causes the arrows switch directions. Tap the button that moves the saw away from your arm and switch buttons if the polarity reverses.
