I have a Ko-fi if you can use Stripe?
Other than that if you're okay waiting I'm in talks about putting the story up on a site that accepts credit cards :)
I can wait, but I'll check the Stripe option if I get time! I know theres a way though to do card payments through itch.io, as I've bought something through this site already (a VN https://red-deer-studios.itch.io/tales-of-bella-ventus-curse-of-the-skyfort ). I don't know what that process entails, but maybe they might be able to point ya in the right direction?
