Pig boy is the most challenging fight so far, energy tennis is a bit tricky to get the timing on cuz it's so fast, but very fun fight overall, definitely my favorite so far
You can stun him by pulling his own weapon towards him? Amazing fight none the less. For someone like me who sucks at 2d zelda i barely managed to beat him and had to refight him for half an hour to 3 hours. Echoes been real fun so far.
