There is a way! Here you go:
> Load your map in the Map Maker.
> Click the "export" button.
> Wait for it to finish exporting everything, then click ok on all the messages that popped up.
> Go to FeralHeart > exports, there should now be a bunch of files here; These are what you use to share your map with other people.
> Right click on your desktop, Hover over "New" and left click "Compressed (Zipped) folder".
> Give that folder a name, then put all the export files from FeralHeart > exports into the new .zip.
> Upload this .zip to a site like MediaFire or Dropbox.
> Share the link with other people!
