i know this question is asked alot, but if i purchase chapter 1-6, do i get all future updates, or do i just get chapter 6?
Just episode 1-6. If you ask me I would subscribe on patreon and I know its a little pricey (5$) for the new build but there is a chance to have a new build's (1-7) beta. But if you are low on money then just wait or buy it now the episode 6 then get the episode 7 again (1.55$ + 1.55$).
Oh and patreon subscription comes with the extra stuff >:)
