Thank you for your reply.
I would like to explain that I have already sent two emails to Itch.io Support (support@itch.io) about three days ago, however, I am sorry that I have not received any response until now.
I have read in some community posts that "Itch.io may only allow refunds within 7 days of purchase". I am not sure whether this is accurate, but I am quite concerned about the refund eligibility due to the relatively large amount I paid.
I hope you understand my concern and sincerely appreciate your assistance.
Best regards
