In the game described by the OP, Nature must invent a law, which must be expressed in a language. So, in the game, there must be a description language.
As to whether (real life) Nature can be said to have a description language: I assess the validity of this concept in terms of its success or failure in explaining phenomena. I wouldn’t be ‘pretty sure’ of any hypothesis unless it were tested.
I’m pretty sure Nature doesn’t have one.
Obligatory XKCD

So, in a true language the results of saying something could be equal to actions?
I’m not sure how to phrase this...
I think say and do: Heat + Air + Fuel and I get Fire?
Hmm...
