Thanks for your support!
I read the FAQ and saw that itch allows us to use Stripe to accept direct payments by credit card from anywhere in the world. I also checked what informations are required to register on Stripe, and it will take some time for me to sort things out to be able to register properly. It's ok if you can't pay, knowing that you wanted to already makes me super grateful :-)
I'll let you know when I'll be able to accept Stripe payments.
