Twine2/Sugarcube2 - re-enable browser's back button?

I guess the title says it all. I made a very short and very simple game using Twine2/Sugarcube2. It would make more sense to me if users could just return to previous pages using the browser's back button. (There aren't any variables that I'm worried about getting messed up.)

Is this feasible? Maybe I'm crazy, but I think I had to alter the code to disable the back button in earlier versions prior to the current Sugarcube?

Thanks.
