If I may, I do not see where you should have any concerns. The price of your game here is higher than the Patreon paid you, so therefore they will only have access to see your game here, not play it for free, unless you make it free. This is just another way to broaden the base you reach. So many here do not know to check for Patreon and vice versus. I think it will be a win-win for you.
Just my opinion. I do not work for either of these two.
Good luck on your game
