So I'm not going to say that the king's fight is incredibly unfair, but its either you get into the right spot and have essentially 100% success rate, pr you don't get the right spot and have a 0% success rate. Maybe making the daggers not always spawn in the same way but making them fake slower may help this because imo the fight right now is insanely formulaic but you can't win without the formula. Also for the winter levels, perhaps its not a great idea to have fast dark proyectiles on a dark background while you move fast

best of luck
