Howdy. :) That's odd. I see the payment, so you should be good. It'll show up on the download page. It should say up top that you paid for the assets, and give a download link. You should see two files, the free one 'mystic_woods_free_2.2.zip' and the one you want 'mystic_woods_2.2.zip'. If not you may need to put in a support ticket with itch.
