I think I understand but, just for the sake of levity, what is the purpose of this mod? What does it do/seek to accomplish?

the purpose is to make the game more fun, at least to me ^^

...By doing what, praytell? Descriptively breathe some life into this. Does it make it harder, easier, just different?
