Wrong game :V
He was referring to Shoot the Bullet.
I got so angry I just turned on Shoot the Bullet and beat EX-4 and EX-6 for the first time.
10-6
Just the ability to find gaps quickly in the bubbles. Practice is all I can say.
EX-6
Start from the middle-left and take a picture.
Than make your way down and right while charging full speed and following the gap between the outermost small bullet and the second outermost one.
You'll know where it is if you just move horizontally from the start.
Hopefully you'll be able to take the fifth picture before you reach the right side.
EX-4
Just static dodging.
EX-7
Suika makes 'lunging' motions, so you can try to misdirect her.
Just be careful to not make her appear outside the screen.
Suika appears about at 173, 150, 129. Hang in there.
8-7
Stream at the bottom and don't stop moving, especially at the latter half.
Go from far left to far right, and don't just take photos before you reach either edge.
At last photo Ran will be so fast she can collide with you if she comes at a steep angle, so try to move a bit more if she does.
