How to Explore Freely:
1. Complete the Story: After finishing the main story mode for each game, you can revisit levels and continue exploring.
2. Unlocked Characters: All the characters you unlocked during the story will be available to play as in these levels.
3. Free Roam: You can move freely around the levels, solve puzzles, collect items, and interact with the environment.
Important Note: While you don't have a designated "Free Play" mode, you can essentially enjoy a similar experience after completing the story.
What's Different:
* No Character Switching: You can't freely switch characters like you might in other Lego games. You'll need to choose your character at the start of a level or use one you've already unlocked.
* Limited Objectives: While you can explore freely, there might not be as many additional objectives or hidden collectibles in the levels after completing the story.
