press the green flag then use either the left mouse button, the spacebar, the W key, or the up arrow key to move your player up and down to avoid the red slates. there are two different kinds of red slates, one stands still, and one moves up and down, but be cautious, the red slates that move up and down can stop at any time.
all by me, inspiration from the mobile app jetpack joyride (laggier computer messes up some of the timing, like "wait _ seconds")
