Yep that's right, which was said to be the easiest of all touhous, I cant even beat it on normal. Let me just give you an example of my runs, in stage 1 through 5 I get like 1 or 2 deaths max. So I reach the last stage with like 4-5 lives, I flawlessly clear the stage and then I reach the boss. And then it all turns into shit, pretty much all her cards are way too hard compared to the rest of the game, even the easy ones with those tiny balls, their hitbox is like twice their visual so I get hit and lose a life. 1 or 2 of these silly mistakes means I can't 1cc it, well no problem I just continue.
And then? I have to do the same freaking stage with 2 lives... so I flawlessly do the stage again and then I reach the boss, and it doesn't matter wich card it is there will be at least one which I fuck up. fucking up means losing a life, losing a life means I only have 1 left, so eventually I cant bomb spam anymore and im left with 0 lives on the last card. Which is the most insane crap I've ever seen on normal, it lasts like 7 minutes and the boss barely takes any damage, using a bomb causes me to lose 1 power which reduces the damage even more! So I try to dodge those things but they are way too fast, so eventually I do hit one by accident, and there's no way I can still bomb once I'm hit.
So, how the fuck do I do this stage? I watched a replay of some1 and he was like the biggest noob ever, he bomb spammed every single card without hesitation and then for some miraculous reason he perfects the last card.

I really need tips, espescially on the last card, even if I reach it I am sure to die anyway.
