Better Main Menu Interface

Just started playing again a recently updated renpy game made by Cosy Cafe and the Main Menu is just so better and different. Is making that menu difficult? My last practice of renpy was months ago and I haven't come across anything that can teach me how to make a game interface just like that. I'm gonna be making my 1st visual novel soon and I don't wanna be seem outdated. Please enlighten me T=T
