It was literally like that. I had a script of about 310 lines and the main function was like 10-20 lines of code. I had a very nice Setup of objects that handled all functionality possible behaviours independent and so my main function was just receiving a user input from another function and add accordingly which included like 3-4 different scenarios that are being handled in the main function.
Just be wary of writing ravioli code which forces the person reading your script to have to constantly jump around it in order to figure out what is actually going on.
