Suggestion: syntax

[n3phos]

Hi

I've just read the tutorial, clearly written and nice to follow!
My suggestion is to add some explanation of the syntax used in the code.
For example, Records are mentioned ( https://www.elm-tutorial.org/en/01-foundations/06-type-aliases.html ), but the syntax for updating a record is not explained.

let
   updatedPlayer =
      { player | level = player.level + howMuch }
in
      ( model, savePlayerCmd updatedPlayer )

Also syntax let in is not explained in the tutorial.

But besides those, i think all is understandable.
