I was getting really frustrated for a bit when I was trying to get that pin...and yes, my scores were actually worse (in the 220's!!) a few times. I think I was just so annoyed that it was distracting me.
I think that I am getting worse because I am trying to get perfect on every screen. When I started I was just trying to hit them all it didn't matter where. Now I am so focused on getting each and everyone one at the star that I am missing some. This just isn't my game.
