Captain Rian is insanely hard to beat. You have no resources at first to tank her hits and the QTE meter is obnoxiously fast. 

Not sure what is the purpose of setting this kind of difficulty just to block players from actually playing the game, let alone actually experience the content you created. 

Combat is incredibly one-sided and RNG-based.

I see, I forgot to disable the enemy level scaling which makes it even harder to kill when players are at a higher level.
It will be adjusted in the next update

i beat her at lvl4 u need to clean the soldier first then heal until you remove her armor with the jump attack counter and then attack/heal and counter till death
