Finally I was able to pay and get the game. It turned out after gamejolt.com . They give a direct link to Itch.io, but their payment page is expanded, with a link to the payment address, which is on Itch.io No. Apparently, the need to specify it is really related to the country of my residence. As soon as I filled it out, the payment went through and the download link appeared. I'm downloading it now. AND THANK YOU SO MUCH FOR YOUR WORK!
THE GAME IS JUST EXCEPTIONALLY GOOD!
