Marisa is mid-tier.
PoDD AI is dumb as fuck. always remember that. it can trap itself when there is nothing on the screen and randomly hit an enemy, but it can also dodge shit every human autobombs. it's sometimes a matter of luck whether you win or not. Yumemi's cloud of death for example is undodgable unless you clear out some bullets with enemies. the swirl of doom can be dodged, but the gaps are tiny, so in that regard, the less yumemi uses those attacks the better your chances at victory are. same goes for chiyuri and her "random shit everywhere" attack. that, coupled with a panic attack, or just a regular level 3, is pure horror. so again, the less she uses that attacks the better your chances at victory. practicing helps to an extent, but RNG will always play a major factor in whether you will win or not. almost any character can go apeshit on your and turn the game into a shitfest you have never seen before if they wish so.
it's a great game. I'm glad someone else plays it.
I'd love to have a game as crazy as PoDD, but with PoFV mechanics (slightly altered to match the game's pace, since the slow charges would help you nothing on PoDD bullets).
