I wouldn't count on it too soon. The game has been getting an update that changes the code at around every 2 weeks, according to its itch.io history. Considering that it costs 20$ as a monthly patreon subscription, just for that version of the game, someone still needs to pay 20$ constantly just to leak that version, every once in a while, with each new minor update every 2 weeks that exists mostly so the dev can change his code, and keep people paying for the new version. you might honestly be better off waiting for the guy to finish his game, which is also somewhat unlikely it will happen soon, since the guy has already started work on his next game, instead of finishing the one people are paying for.
