Sorry for taking so long to give it a shot, but:
$ ./The\ Heart\'s\ Illumination
Error:
An assembly specified in the application dependencies manifest (The Heart's Illumination.deps.json) was not found:
package: 'MonoGame.Framework.DesktopGL.Core', version: '3.7.0.7'
path: 'lib/netstandard2.0/MonoGame.Framework.dll'
Soooo… it’s broken. Or at least, it’s looking for a nonexistent directory.
