I think Patreon allows you to use credit cards.And, I recommend that you buy things there because itch may ban my whole account due to a very small mistake I made several months ago. I fixed it but they seem not to forgive me.
You know? I've been already shadow banned here because of the reason above. I fixed it and apologized, but no answer and the penalty went on. Their next movement will be more severe I guess. Why so harsh? I don't know, maybe they just feel disgusting watching my art, or can be a race matter. Some people hate JP.
I'm not saying "don't use itch". It is they that don't want you to buy my things on this platform.
So just go somewhere else if you wanna buy my games or comics.
They can even refuse to pay me by demolishing my whole account. If they do, I'm pretty sure they'll do it all of a sudden without any explanation, which means when I add something to the game you'll get nothing here because the whole account being banned and destroyed.
