1) Only jump/kick when you have a good chance to get the ball between opponent's defender and goalie, otherwise stand still and wait. 2) Let opponent do your work. 3) Repeat steps 1-2 if unsuccessful.
The ever so hopping green quests book is annoying because it hops just because I don't bother to read all the dozen new quests that want to be solved at once.
I just recorded my highscore-game of 65.143 points on city level just in case someone wants to delete it again like last time. Before the high score reset I had a legit score of over 1 million and I could reach over 200 or 300k within an hour easily. Cheers.
