Hello! I got here from the gumroad page-- I have had it open in my browser for a long while, and just recently noticed it's unavailable to buy there.
I have tried to buy it here, but it gives me an error (422) when trying to pay with paypal (see image). Is it something expected (as in, it shouldn't be available for purchase), or is it a problem with itch.io itself?
Thanks in advance and have a good day.
