Sorry, I'm afraid I don't understand what you mean by, "if the choices were 'navigated' on each screen".
One of my favorite systems for navigating text is the one used in the game Disco Elysium. It allows you to choose options either by clicking on the choice with your mouse or by pressing the corresponding button on the keyboard (like what your game does). The choices appear just as regular text, but when you hover the mouse over them, they change color.
Sorry yeah I think I didn't explain it too well, It would be sort of like you can select options by moving up or down as if you're in a menu selection for a moment, sort of. I don't actually prefer that way myself.
The video you provided really helps actually where it shows the text changing color when hovering the mouse over the numbered options. I think I may prefer that way, thanks for providing the video clip. I may consider to play that game you linked there sometime as well as it seems fun. Thanks for your feedback, it's very helpful!
