Thanks to your feedback, we have identified a few battles that seemed odd regarding the progression of difficulty in the game.
As a result, the following three battles have been adjusted to offer an appropriate level of difficulty:
World 2, Chapter 2, Battle 1
World 3, Chapter 1, Battle 1
World 3, Chapter 4, Battle 2
We hope that you will enjoy these changes! Best of luck out there!
