You suck in gems with shot A and to suck in gems with shot B you have to either stop shooting or switch to A. To simulate this i have set the controls from switch to hold.
Please note that the gems have a glow for a few moments, you have to nearly point blank the enemys to get the gems in this glowing state.
Maniac scoring:
Basics:
You build the combo meter while killing things with A or holding A on big enemys. When you kill things with the combo meter in red they give you double the amount of gems. The Idea is to build up your combo meter shoot at a big enemy with A and kill it with B while in the red zone...

Thanks a lot.
I'm definitely going to do some more reading today. I'll change the shot from switch to hold as well. The glowing gems are the key to original mode from what I can tell. That's going to take some practice and memorization to improve. I got the first extend by accident last night but now I know where it is.
Edit: looks like laser(blue) sucks in gems on the ground.
