Hello, dragtonrod,
I love your game and I will happily donate if this platforms offers anything other than paypal, since I have extremely negative experiences with them.
That being said, have you considered adding Digivice support to your games? Something like being able to upload digimon from the Digivice to your game. I think that would be dope. There are several communities on Discord which I am sure you are already familiar with, who have also already done great things.
Regards.
