You forgot the .pck file, you must add it, we can't play without it, or you just can export only the .exe but there is a certain thing to mark at the export on godot.
Cool to see other users using Godot. Unfortunaly you only uploaded the .exe file. There should be an additional .pck file in the folder you exported. You have to share this in a zip. There is also an option to build everything in a single exe if that is what you preffer.
