My favorite boss so far holy shit

>forces you to stay at a distance
>does an attack you can't see the startup of from offscreen

Finally killed this stupid bitch yesterday, thank god. She's actually fun in a vacuum since she lacks bullshit enemy spawns, has a clear and concise moveset you can react to with enough practice, and is the one boss I've fought so far who I feel deserves to do two masks of damage with each hit, but the aids-tier runback every time you die and that stupid fucking death explosion that exists solely to pull the rug out from under your feet when you kill her the first time really soured any enjoyment I could have gotten from fighting her. Sadly I know that Act 2 is fairly meaty and that there's an Act 3 beyond that, so things are only going to get worse from here.
