How do I buy the Sponsored version here on Itch.io? I don't see any link for Sponsored version. I tried to pay the 200 Yen on your CI-EN page, but my credit card will not work there.
The download button in this page, then pay some $ and u'll be able to play sponsor version
You can try to buy DLsite point and use it for payment.
But the content there will be censored
