Fix the fcking camera. More than once have I been gypped out of an otherwise easy shot because the camera didn't go back to the center. Yes, this game is very frustrating and not even worth playing imho.
oh and if someone is having trouble getting the hard badge, i'd suggest playing around with the modes and find out which one you're best at, and then focus on collecting the yellows. more yellows = bigger combo and bigger cursor = less you have to work to get lots of points.
