Hi, Krishna,
I meet the similar issue as Vainquit.Something different is that I success paid for this assets but I can't receive them.... (Minifantasy😎Summer Sale😎)
I have reported this issue to support team of itch and your email (minfantasy.assets@gmail.com).I think support team of itch will not solve it immediately. But I want to use your assets to make game as soon as possible.
Please help to check it in your email.I attach all the detail on it(purchase information).
Thank you.
