Few tips I wished I knew before getting crazy…

. You can cycle only through enemies with the combination L2/R2 * L1/R1. Clicking L1/R1 moves backward/forward between enemies. The enemies get selected, not just focused
. You may want to set the controller as dpad-dpad/buttons-buttons. It would be better if you give it a try now that you just started. I find it a bit less confusing, at leat the buttons descriptions are properly placed on top of them.
