How do i make saves for metroidvania?

I'm making a Metroidvania game and planning to release it on Steam. What's the best way to implement saving so that it just works? The standard way or through Local Storage? I started using Local Storage and realized I have to manually write and save a huge number of values, which is very inconvenient. Can I just use the standard saving method and not worry about it?

I would not recommend using the built in save system. It's a pain to work with when updating your game.

With local storage, just save everything to dictionary keys and then save the whole dictionary as JSON to local storage.

Thanks. I will try it.)
