Think outside the box

Don't be afraid to experiment with different approaches to solving puzzles. Try using the environment in creative ways, or combining different elements to create new solutions.

Watch your step

Many puzzles require precise timing and positioning. Make sure to watch where you're stepping, and be aware of hazards like acid pools and turrets.

Use the "quick save" feature: The game's "quick save" feature (F6 on PC) allows you to save your progress at any time. Use this to your advantage to avoid repeating puzzles you've already solved.

Play co-op
