The hide button does work to hide the text box, but none of the others actually do anything. I can’t quick save or load, I can’t see the text history, and most importantly I can’t even open the menu. How am I supposed to save like this? This game doesn’t have scene replay so it’s important I make saves before every h scene.

Same problem here. Although for me it seems like both the Hide button and the Q. Load button work. All of the other buttons do not.
