This is advice that can be applied to many metroidvanias and rpgs, but save often. It is a lifesaver for when unexpected difficult situations happen. Benches will serve as your "save room"

For Hollow Knight, I'd say take your time to explore and get a feel for the world. There is a quick travel system that is also very useful, I recommend unlocking all waypoints you encounter.

Also slash your nail at as many walls as possible. There are a lot of secret rooms & passages.

Thanks for the advice.
