The visual interface on eps 6-8 was programmed by an external dev I bought. I'm terrible at finding out this stuff, but I'll do my best to see what can be done for Season 1!
Since this game was made with RenPy this should be pretty easy...
Their Documentation on that: https://www.renpy.org/doc/html/gui.html
You could even go ahead and copy the default buttons from the default RenPy example project... (The features included in that would be absolutely sufficient..)
