Looks like the download is windows only. You should label it as that in your dashboard.
We'd love to try it out. Are you able to upload a macOS build? You can send it to an external site (google drive, media fire, etc) and just have a link here so we can play and rate it during the rating period.
To build for mac you just need to add the support files in the hub. Unity Hub > Installs > Select the editor version you used for this game > 3 dots > Add mac build support. Then inside your project > build settings > select macOS X standalone.
