I understand that just i have seen other games on this engine have the option to hide the ui on windows and mobile versions as it has seemed to be a feature the renpy ui can have that i think would improve the experience as the ui and characters overlap especially for any who prefer to us there phone. I know the game ravager has the hide button in the same line as the back skip and menu options and until i played a few more renpy games i thought that was standard. I understand it isn't a priority was just a idea i had from previous experience.
Best wishes and thanks for the game so far looking forward to the next release
