There's only version 0.1 yet.
I don't fancy playing monthly for a game that isn't there. When Patreon has an update, let us know here plese
Then I'll gladly join your Patreon for a single month to get me the game. In fact, you should consider to offer the latest version here for pay, if or not next to a free version.
The devlog doesn't even mention at all if there's a newer version already.
