The UI in this game is completely horrible. Using the default Ren'Py Interface for a game like this is just laziness and I can't stand the quick menu on PC, as it's completely useless in my opinion.
It's not perfect, but I did a hash job. Can't share it since I basically altered a bunch of game files since I'm not an expert on coding in Ren'Py. I really wanted to eliminate the textbox background, but then I couldn't see the text under certain conditions without adding text shadows and I don't know how to do that. Some of the basic background replacements are taken from the
Crimson High Dark mode.
Might re-do this at some point if I figure out how to make custom edits without altering the original files, as well as adding shadows to the text so I can get rid of the damn text background.
