Not anymore. Patreon bullshit, payment processor prudes against incest, buncha pricks. You'll need to get an older version, pre 0.7.232.
IMO the crew should switch to SubscribeStar if they can, assuming of course they still want incest to be part of their vision for the game and want to be funded via something that could fill Patreon's shoes.
You could actually find an older version on another site if you're willing to scrounge, I'm just hesitant to actually provide you an older one on this forum lest Patreon bring down some sort of judgment hammer. Remember, every six double dildos are merely one.
