CI is green but I have a couple requests. The dune version required is 1.2 as described in your dune-project file, this should be reflected in the opam file as well.

Also, looking at the dune-project file inside the archive, the version field seems a little odd:

(version v0.2.1)

It containers the v prefix but the version number does not have it, is there any chance that could be changed? The version field is stored in the dune-package file and I'm not sure how it is used but this can be used in the future anyway.
