Does it gets harder?

I started playing the game and fell in love with the art style and character design. The game has an amazing personality! The movesets and combat are also pretty satisfying. However, I have to say I am a bit bored with the difficulty level... I explore the areas looking forward to the boss battles but they are a bit anticlimatic. I have killed both the urn witch and frog king and felt like both were sadly so easy. I loved the witch's moveset but the king frog was so monotonous. Does the game get more challenging than that? I would love to keep playing it, but for now it is not scratching the itch I have for challenging combat.
