The sensitivity when "flicking" the soccer ball is completely out of whack.
The tutorial says for harder kicks, flick faster. However, when flicking faster, the ball consistently goes JUST OVER the top of the woodwork, no matter the distance of the shot. Flick any softer and the ball is a lame duck and the goalie is there waiting for it.
