The game hasn't been for sale on Itch for some time, unfortunately. If you'd like to buy the full version, you can do so through Steam or SubscribeStar (links are above in the description).
I just recommend getting it on Steam
You can't get it on Steam directly in certain countries (example: Germany).
If there was a way to obtain a steam code either from the Devs directly or via a third party website, I'd gladly do so.
Steam codes are available to subscribers at the $20 level, just send me a message on SubscribeStar!
