What is this file?  Are these sources or is this a binary image?

Is the “.love” file the source archive?  In the repository I only see
“.lua” files.  Shouldn’t we compile them from source?

This looks like you are creating a starter-script which is pointing to
the source. This will not work, since the source will not be installed
when installing the package.

You want to

- copy the source file into (string-append out "/share/" ,name)

- create a starter script

I also suggest using a shell-script as starter (instead of a guile
wrapper), since this is more natural for me.

It's both the love2d package format and source archive [1], which is
just a zip file of the project directory.

Yes, but it works.  The source is referenced by the script, so it will
be downloaded into the store.

OK, both are fine to me.
