This is just a 2d simulator of an airplane. Press the up and down arrow key to change direction. Press the left and right arrow keys to increase and decrease throttle. To take off, point the plane upward and increase the throttle. To land safely, put the throttle low (1-20) and point the direction downward. But not too much. Also, you have a limited altitude. If the air thickness reaches 0, then BOOOM!!!!
I'm supposed to give credit here. So yeah, go check out the original NAO!!
