The walls of text are a painful slog to get through on desktop. Separate it out into sentences, give it a lot of padding away from the edges of the screen (especially the left & right edges), increase the font size, boost the contrast some more, and throw in a function for reversing to previous dialogs in the event of a double-tap like many VNs do (such as the mouse scroll wheel), and this becomes a lot more playable. In its current state, I'd just be skipping all the dialog, and I don't think it deserves that.
