Someone on reddit tried . It seems like itch only allows "purchases" to get the keys. Probably a measure against key farming bots.
I was kinda surprised by this TBH.
It is set up to give keys. But it seems like when you make it free it doesnt?
Could you mail a spare key on catalanicsurya@gmail.com
I was planning to gift the key to my friend. Thanks
I can! I have now sent you the email.
