Hi there ^^ you can exit the extras screen by hitting the escape key on your keyboard, as with any other Ren'Py game. I apologize if this was unclear.
I also apologize if the lack of voice acting was offputting to you, but we made no claims of having it and chose not to include it early on in development because we knew we would not be able to implement it effectively within the time constraints of the jam.
As for the motivations being silly, well... it's a comedy game, they were meant to be pretty silly, so I'll take that as a compliment LMAO. Thanks for your feedback.
