Okay, I'll PM you! In case others have this same question, Patreon is a subscription, but in my case it works exactly the same as just buying my builds here on itch.
For now, I'm not charging monthly, but "per release", and I charge a bit less than on here. Paying $2 will get you access to that month's build when it comes out, and you will only be charged if it comes out, meaning that you won't pay on months that have no release. The difference is that I don't think you will get access to previous builds, so you might have to wait, though I'm not 100% sure.
