Hi there! Good question. The "noreturn" flag works in conjunction with the "$return" function to prevent loops. So for example, when you visit the "stats" page, then click the "styles" page from the menu right after, pressing the "return" button will bring you all the way back to the story (instead of back to the "stats" page even though that was the last page you were on). The navigation arrow doesn't use the return function - it just goes back to the previous page, which is great...but I figured if there's a chance someone doesn't want to keep the navigation arrow (I don't like having a back button in my own game, for example), I'd better cover the bases with a proper "return" button for the menu pages. Thanks for downloading!
