Beating king dice with a perfect was surprisingly easy. Its all about figuring out the mini bosses leading up to the final phase. This game is good.
I mean, once you get a hang of the
dice roll, it's functionally just a 4 phase boss fight with a bit of a cooldown and a chance to heal between each phase, and a hard final phase. No different from Baroness Von Bon Bon who sends out 3 random snack 'mini-bosses' before her final phase. And she even attacks you when they're out.
