Sorry for the confusion The way the game connects with the theme is that in some types of games like Angry Birds or Subway Surfers you gotta collect the most collectibles (stars in angry birds) in order to get a new high score or advance onto the next level This game takes that concept and flips it on the head so in order to win you have to avoid the fish and not get any new high score to win!
Also thanks for the tips!!! :-D
