This update is a step backwards on the iPad Mini. All the control and info elements are larger, cramping the screen. They also look fuzzy. The tree list on the asteroid panel now overlaps with the word 'trees', so asteroids with more than 4 trees have tree icons behind the word.
I much preferred the game before this update. The only improvement has been the defense tree icon in the asteroid panel. Oh, and Laser Pods upgrading along with their home asteroid, that's better too.
