Marisa done. Cleared with my first credit that got out of the stage 1 cage but I did have to practice for a day first. Although I didn't bother enough to learn her stage routes properly so good boss performance carried me.
Her shot does okay damage so Marisa isn't too bad actually, just that her bomb just really sucks. It does really low damage so some spells like Lilies can still kill you even after bombing them twice. Those micrododging spells that Junko has gave me more trouble than anything though, they're really easy as Reimu but the slightly bigger hitbox makes them really bad when Junko decides to move down the screen.
Anyway, easy part of the game over with. I gotta figure out how much practice I need for an LNB now. Probably a lot. Definitely gonna have to get competent at PDH, at least to a point where I consistently only die to it once.
