Thanks for letting me know. Included is a Steam key, so you can download the working version from Steam. But, I'll get a new and correct version uploaded here too. Thanks!
Information online seems to vary. Itch.io should show a 'request key' button either on the main AWCA page, the Download page or on your purchases page.
If it still does not appear, please email me from your paypal email address at email@example.com and I'll send a code.
EDIT - I'm showing some redeemed keys, so it must be possible!
