Here are some ways to navigate around boulders:
* Use the Strength HM: This HM allows you to move boulders out of the way, opening up new paths.
* Find a different route: Many areas have alternate paths that bypass boulders. Explore the surrounding area and see if you can find a way around.
* Look for hidden passages: Some areas may have secret passages or hidden paths that allow you to pass boulders.
* Use Fly: Later in the game, you will learn the Fly HM, which lets you quickly transport to locations you have visited before, avoiding obstacles altogether.
Remember, Pokémon Platinum is a game designed for exploration and puzzle-solving. Don't be afraid to experiment and try different approaches when you encounter obstacles.
