Hello! Thank you for support! Are you asking for a singe donations or about to pay on itch, patreon via crypto and etc?
three of a kind.
if the payment options got accepted for a single payment for both platforms the early access version is easier to get.
on the side note:
ideal is every Netherlands Bank.
paysafecard is a worldwide web bank similar to PayPal but easier to use and access.
for cryptocurrency you could gain a decent amount of it, burn some of it raise value and get rich
via crypto or any other sources for single donations and if possibly subscription as in you make purchase able subscription prepaid meaning you get in between 1 to 12 months premium access depending on how much you payed and so basically a own account with login for subscription code, but you can still play, but use premium functions
