Yeah, unfortunately it appears that the game is unplayable. As far as I can tell, nothing uploaded is actually specific to the game (just stuff from the Godot engine), so there's nothing that can be done to get it to play as-is.
Since the ability to edit uploads during the rating period is disabled by the jam, there isn't really a way to fix it. There's only <12 hours left to the rating period, though, after which you will be able to fix the upload at least.
