Hey there! Sorry about this one, we just found it.
It's currently fixed on our site, but still broken on itch.io. If you want to save to disc and import into our site, you can back up until the point it breaks, then moved forward. Michael will (incorrectly) imply he saw the kitsune spirit, then you should be able to save and get it back into your game of choice.
Otherwise, it should be fixed on Itch.io by tomorrow. Unfortunately, that one requires slightly more web skills than I have to package up, and our web master is out tonight.
