No worries! So the main menu buttons just take the regular button style, in styles.rpy - style button and style button_text. Changing that will change all buttons that inherit from it, so if you want to just change the style on the main menu, I suggest you write style_prefix "mm" on the main_menu screen, and then your buttons will have the style style mm_button and style mm_button_text, which you can adjust however you like. You can also directly assign a style to a given button, e.g. textbutton _("Start") style "main_menu_btn" will make that button use the styles main_menu_btn and main_menu_btn_text. Hope that helps!
