Here's why:
* Game Mechanics: The game doesn't allow for widespread destruction like that. You can use spells to break specific objects, but not to completely destroy environments.
* Gameplay Design: The developers likely chose this design to keep the game fun and engaging for younger players.
* Focus on Puzzle Solving: Many of the levels in the game require specific actions and interactions, and allowing for uncontrolled destruction would break the intended gameplay.
While you can't explode everything, you can use spells like:
* "Stupefy": This spell can stun enemies and sometimes break certain objects.
* "Wingardium Leviosa": This spell allows you to lift and move objects, which can be useful for solving puzzles.
* "Reducto": This spell can break some objects, but it's not as powerful as you might think.
Remember, you'll need to find creative ways to use these spells to achieve your goals in Lego Harry Potter: Years 1-4. Have fun exploring the magical world and solving puzzles!
