The download link is taking me to a DropBox upload, and the file appears to be an exe.  Is this intentional?

Same question. This makes it so the itch client can't access the file. It also comes across as a bit sketchy.

The exe is an installer it was unknown by windows defender however installed without issue and into a custom location I specified.  The game plays very well with some minor sound issues with hearing the narrator for me.

Itch.io doesn't host files larger than 1 GB so I'd assume that is why dropbox was chosen
