Hey, thanks for the questions. As of now you will only get access to updates in the month you subscribe, however you will always recieve updates a week or more before any other platform. I'm also adding more content for patrons over the next little while, for example Ruby patrons get early access to new monsters, and Ruby/Gold patrons will recieve new animations before other platforms. Ruby patrons also get access to different cheats, like infinite free items and spawning in different monster species for free.
I will also be adding more patron exclusive content as the game becomes more complete, and I no longer have to focus on bug fixes as much. The Itch and Steam versions doallow you to speed up time now, I haven't updated the patreon pledge level graphics in a while, but thank you for the reminder.
