I talked to the itch.io people. This seems to be a bug on their side. They're looking into it.
Thank you for looking into it.
Alright, I have re-enabled things. I hope the reward works now. If it still doesn't then I guess I'll get in touch with the itch support again.
I am sorry to say, that the community copies still do not work as intended.
A friend of mine bought a copy for me, so I own a copy.
I really like the game for different reasons. I should probably start a new thread :)
Love to hear what you like about the game and sorry to hear that about the community copies. I will disable them again and reach out to itch support again. Thanks for letting me know!
