The concept is nice but the biggest flaws I'm seeing in it is how the snowball does not disappear once it hits the ground, so when a new set of bars are coming, I am forced to move to the floor in order to go through the spacing and lose life once I make contact with the snowball. Best to have the snowball fly across the screen and disappear, instead of annoyingly hitting the corner of the screen and falling to the centre. Also, the snowing animation is very distracting. Consider removing it?
