Guys, I'm fighting a giant loving robot of the swarm at level 9 on classic... I'm too afraid to unpause.
EDIT: Toss some tips my way if you know the robot's patterns.

when you see a stuffload of energy balls at the top of the screen the robot will raise the stage so they hit you
when you see it grow a red tumor and it starts tracking you around he will slam it down and explode then the spore-like things will explode like X bombs
when it does a hand slash motion wait for like a second and block or evade, thats when the actual attack will hit you
when it makes two grabby hands appear just roll through them so they dont get you
