[bug#35411] [PATCH] Add hedgewars

Oh neat, this is great!

Let me go through the rest of the patch:

> +                    (changeset (string-append version "-release"))))

Is there no release tarball?

Do you know why it fails?  Is this an upstream problem or likely
something to do with Guix?

Is it really necessary to compile with Clang at all?  What happens if
you compile with GCC?

Is this not actually a native input?

I think this also might be a native input.

Please remove the final exclamation point and the comma.  Maybe remove
“Funny” because that’s subjective, but feel free to ignore me.

The description is a bit long.  We don’t need a list of weapons or the
rules of the game (“dies when it enters the water”).  Could you try to
shorten it and make sure that the first sentence describes what this is
all about?

Thanks for packaging it!
