That's weird. You should be able to use credit card or paypal. Send a message to itch.io telling them about your issue, or support us on patreon for a month. There the game has the same price and patreon accepts paypal and credit cards.
I'm sorry, I tried really hard and the card was declined on patreon as well. Is there another way I can pay(other than cards)?
Paypal or stripe should work.
