2 of the Noble Nickel locations aren't possible to get out of 0x so I just resort to suicide. There's a lot of enemies in the final stretch of the level so I just damage boost through there. It's definitely not as elegant as killing all the enemies, but meh.
I was kinda afraid the Quarantine Woman fight was gonna go awfully but then I learned she was weak to Flash Stopper and I wasn't scared anymore.
