Hi Stephen,
Patreon has a list of accepted payment methods and currencies here. This includes:
- PayPal
- Apple Pay
- Venmo
- Visa
- Master Card
- Discover
- JCB
- Diners Club
- 3DS
Patreon creators have no say over what payment methods can be processed. I hope one of these will work for you. Even if you're unable to support through Patreon, I appreciate your enthusiasm for my game all the same! The game will always be available to play for free; Patrons just get early access to new episodes early. Thank you so much for checking it out!
