What does enabling 'saves' do in the options menu?

Question

I have a feeling it is a joke, like the "achievements" one, which gives you an achievement called "achievement". But I don't want to lose my progress by not enabling it.

Answer 1

Enabling saves does allow you to save in the middle of a run.

Since the game rarely takes more than 5-10 mins (with perhaps one exception), this isn't necessary but it allows you to save and reload so you don't have to keep replaying the early bits of the game.
