Some problems

(1) a single package per patch (minetest-naturalslopeslib can be done in 
a commit before minetest-exile)

(2) no superfluous version prefixes -- remove the "v" from
    (version "v0.3.8") and replace (commit version) by
    (commit (string-append "v" version))

(3) naturalslopeslib is lgpl2.1+, according to the README.md

(4) In minetest-exile, input labels can be avoided by replacing

+                        (add-after 'install 'install-dependencies
+                          (lambda _
+                            (symlink (string-append
+                                      #$(this-package-input
+                                         "minetest-naturalslopeslib")
+ 
"/share/minetest/mods/naturalslopeslib")
+                                     (string-append
+                                      #$output
+                                      "/share/minetest/games/exile/"
+                                      "mods/naturalslopeslib")))))))

(5) Going by https://content.minetest.net/packages/Mantar/exile/, more 
specifically its Website link, the home page is 
https://exile.planetofnix.com/wiki/pmwiki.php?n=Main.HomePage

(6) According to the content.minetest.net page, you forgot to mention 
the CC-BY-SA-3.0 license.

(7) Patches need to be sent to guix-patches@gnu.org, not guix-devel.

(8) I found a directory utilities/ -- IIUC, these bundled mods aren't 
actually used by the game, so they could simply be removed in a snippet 
like minetest-naturalslopeslib

with

    (add-after 'install 'install-dependencies
      (lambda _
        (symlink (search-input-directory inputs 
"share/minetest/mods/naturalslopeslib")
        (string-append
          #$output
          "/share/minetest/games/exile/"
          "mods/naturalslopeslib")))))))


Some things I can confirm:

(1) the hash for mintest-naturalslopeslib matches
(2) likewise for minetest-exile

Note: I didn't actually try out these patches.
