I like the omninous glow of the character and also the sounds. I think there were problems with the export though :(
I think you exported the project instead of the game (Meaning, I have access to the internal files).
You also gotta tell itchio this is an Windows export, otherwise people cant install it from the Itchio App. Have in mind that for GameJams, Web exports are usually better too. You may want to test how to do it with a private project, so by the time you participate in another GameJam you'll have the pipeline ready!
Lastly, in your Godot project, play with the options in Project settings > Display > Window. Specially the ones at the bottom under "Stretch" (Mode, Aspect, Shrink). Test it with fullscreen disabled and resizable enabled.
