What, like hitting and dodging him...? XD
Forgetting the fact he is much faster and more aggressive, dodging his combos - which reach 5-6 moves each in this phase as opposed to 3 - require different timings, he does way more jump attacks, fires more placenta juice (at different intensities, angles and number), his moves are entirely focused on close range attacks as opposed to the ranged attacks in the first phase.... etc.
I'm not calling you out, I'm just baffled how you could do that; he changes up nearly everything he does.
Never ever ever give him space, since that's when he shoots that crazy ranged attack that hits everywhere. You really do just have to be aggressive and good with your dodge/parry timings.
