Turns out there's extra files you left in there! Steam related things.
Oh interesting! I'll fix it. I tried to make the game easy to export between steam and Itch.io. However, it obviously needs more work lol.
I'll let you know when it is updated here.
In the mean time, you can always play "Besmirch Demo" on Steam!
Here's a link if that's helpful:
