sorry for the late reply. My suggestion is to start learning the programming software c# (pronounced c-sharp). BF is developed using Unity engine and Unity uses c# for its coding. DNspy lets you view the c# code for the game and edit some of it. Once you know some of c# works, you can dig around in the files and know what to manipulate. You won't be able to do anything too big with it, but it can be insightful.
