Hi there.
I would approve and welcome you to apply for a refund with itch.io if that is what you want. If you review the README.txt document, you can find at the bottom the section about Patreon and what links you need to follow to sign up. Additionally, you could just reach out to me on Discord and I'd be happy to help. I apologise for being vague about Patreon, but we're just trying to keep things clean and anonymous for people.
