You should have received an email from itch.io with your download link when you purchased the game.
If not I suggest to ask itch.io support because I have no control over the payment system unfortunately.
Viewing post in Bought game on Sidequest, might have messed up?
when Buying a game on itch, and then an update comes a day later, how are we supposed to update without paying again? No one should have to contact EACH developer for their purchase.
This needs a fix. How do we update purchased games from itch when it demands payment again?
