You pay for the current version and get future versions all the way to the full release as we sincerely appreciate people supporting us at this early stage.
I will surely support this project, if I may ask, how many people are working on this project?
Great to have you on board then! We're currently a team of two, and we've become quite efficient working with this team size. We will soon start doing dev streams for a look behind the scenes for our patreon followers, too.
