On macOS Catalina (10.15.4), v1.0 won't run, but it looks like that's because /Ruins.app/Contents/MacOS/Ruins isn't marked as executable.

Not sure if you can fix that on your end and update the package? (`chmod +x` fixed it for me, I should be able to zip it back up if you don't have a Mac / Linux machine lying around.

Uploading an updated zip as we speak. This is just a really annoying bug with Godot's package exports at the moment.

I can imagine! Glad the fix seems pretty simple, and I love the concept. Thanks for posting it on Twitter!
