Does the game freezes at startup? I can't manage to reproduce the bug, but I know someone who can't launch the game on windows neither.
Thanks for providing the source. I was able to play it using the Godot project.
I like the audio and the car animation.
I was able to export a windows exe using Godot 3.1beta4 and the export worked for me. Not sure why I couldn't run your export.
