Best way to save my game?

Whats the best way of implementing a save??

I heard that when we use the save function , it crashes to some people?

Or are those dudes just trolls?

I never experienced the game not saving but some of my players are complaining about that...

I use the prebuilt save function of construct 3...

Do I need to use LocalStorage?

System Save action saves absolutely everything (except for objects with NoSave behavior). It may work for many games, but sometimes you don't want to load some data. For example, you have a volume setting in your game and you reduced volume to 5%. But loading an old save will also load old volume value which was 100% when it was saved. Avoiding things like these is quite difficult. That's why sometimes it's better to make your own save system, where you can control what data is saved or not.
