Invalid '.zip' project file.

Hi. I just downloaded this project as a .zip file and wanted to import in Godot 3.2 nightly but unfortunately I do get the following error message:

> Invalid '.zip' project file, does not contain a 'project.godot' file.

It is possible to make an actualisation of this project to the newest Godot 3.2 versions and to have the required 'project.godot' file included?

Thank you.
