Hello, UI designer here! đź‘‹
We really appreciate your feedback! (and the rest was heard loud and clear, we are really glad you enjoyed the demo so far!)
The textbox UI is shaped the way it is as a deliberate mimic of the mainline Ace Attorney Steam/console ports (it is in fact the exact same dimensions). Quite honestly I agree that it takes up too much space, haha, but we thought it appropriate to use our UI to evoke an experience as close to the original games as possible, with some extra Franziska flair. (The extra space also allows a little wiggle room for those using the accessibility features to increase font size without it clipping out of bounds).
If you'd ever like to see more of the screen in certain situations, you can always temporarily hide the dialogue window with the H key!
Thank you so much for playing!!
