I hope you mean the textbox and quickmenu buttons, because then there is. Try pressing H while playing the game. This schools switch between three different modes. Normal textbox, invisible textbox, no ui.
alternatively, you can also configure these modes in your preferences tap
Thanks, worked, appreciate it! Also wanted to say that the game is fantastic. Solid story, great pacing (so hard to do in these games), wonderful characters, great artwork.
