Number Guess FRVR

Number Guess is an arcade game that's all about speed. You'll first be given a number at the top of the screen, this is going to be your reference number. You'll then be given a number at the bottom of the screen with 2 arrows next to it - one pointing up, and another pointing down. You'll need to choose one of these arrows to answer just one invisible question - is the number at the bottom higher (choose the up arrow) or lower (choose the down arrow) than the reference number? You'll be given only a couple of seconds to answer this, missing even just one number will get you a game over, so make sure to be quick - but not too quick as to cause mistakes!
