If I were to pay for the Patreon once would I get permanent access to paid updates, even if I couldn't stay subscribed? I want to support the game but can't necessarily afford to subscribe every month.
You would only have access to the paid version for the month that you're subscribed, but you won't necessarily need to be subscribed all the time. I'll be making clear announcements regarding new content whenever the game receives updates, so you can feel free to subscribe and unsubscribe whenever the content seems worth it to you.
