Hi there! Unfortunately I do not support any other payment processors at this present time. However, I would still like to help you! As an alternative, you can simply make a Lunch donation on my Patreon page (https://www.patreon.com/javit). Once you sign up, send me a private message and I can activate your itch.io access accordingly. You will get access to both Itch.io and Patreon benifits, and if you decide you no longer want to support the project, you can unsubscribe as you wish.
