For Cirno's first nonspell, I find it much easier to misdirect only the first blob of bullets, then the next two can be micro-dodged. It helps to start the battle off to the side.
Patchy's lasers are super easy if you do them right. (The first wave can be dodged by standing right in front of her, but that's not neccesary) I forget which way they rotate first, but I'll assume it's clockwise. You'll want to move to the left, then stream to the right. You should reach the middle of the screen at the same time as the rotating laser, but it will disappear once it gets there. Then keep moving right to avoid the counter-clockwise lasers. She'll stop for a second then repeat, this time starting with the counter-clockwise ones. You should already be to the right side of the screen, so now just do what you did before, only moving left this time. Obviously, if she starts off with counter-clockwise, then you just do the opposite of what I said here.
Also note that the hitbox for the lasers goes away long before their sprite does, so once they've stopped moving at the vertical position, you can pretty much go right through them.
