/* Obstacle Course by Travis Pynn
Red walls are on the ground
Green walls are in the air
Yellow walls are tall, so they are both
You can avoid red walls by flying over them (holding mouse button)
You can avoid green walls by going under them (releasing mouse button)
You can only avoid yellow walls by going around them
You will slowly gain speed as your score increases
Try to get a high score! */
