Not a good look only allowing access via a subscription. No one likes paying for a subscription and no one wants to go through the hassle of making a payment to you on patreon, getting access, then canceling the subscription to avoid a recurring payment the following month.
People just want to buy your game and enjoy but having patreon be the sole way to access your game is just asking for piracy.
It's a shame. I was planning on purchasing multiple versions of your game from itch after I got home from work today, especially since I want to support your work after being delisted from steam.
