You can switch characters by progressing through specific levels where they become available. Explore the environments, and you will find opportunities to unlock and play as different characters.

Utilize a combination of jumping and dodging to outmaneuver enemies. Timing your attacks is crucial; aim for enemies when they are vulnerable after they attack.

To find hidden gems, thoroughly explore each level's nooks and crannies. Use your character's abilities to reach high places or hidden areas. Remember to experiment with different skills.

If you're stuck, take a moment to reassess your surroundings. Look for switches, platforms, or items you may have missed. Here are the steps to help you progress:
1. Backtrack and explore previous areas.
2. Check for any unactivated mechanisms.
3. Experiment with different jumping techniques.
4. Observe enemy patterns for potential clues.

Puzzles often require observation and experimentation. Look for clues in the environment and use your character's abilities creatively. If a puzzle seems difficult, try approaching it from a different angle.
