Hello!
I have a question. I read the "Integrations - Patreon" section https://itch.io/docs/creators/getting-indexed and I have a question about additional in-game content related to Patreon.
I want to publish a game on https://itch.io/, but my game is supposed to have some additional monetization features through https://www.patreon.com/.
At the moment Patreon redirects subscribers to my website, where they receive a game key. Then subscribers gets a key code and enters it in the game and gets some additional game content. And different subscription levels allows subscribers to get different game keys.

But is this method of monetization this allowed on https://itch.io ?

Thanks!
