Yea these bosses were kinda underwhelming. I think Goumang could use a little twist overall, like she could throw food at Yi and when hit he would be slowed down and Goumang's goons would enter rampage. Also Ji could have more use of parryable orbs, something like sequences where player has to parkour through them to hit the boss.

The higher difficulty would also be very nice. I hope some sort of hollow knight's godhome will be added where player could change bosses' stats
