Alpha is for 20+ patrons, 60-70% of what is planned to be added in next public release, 1 month after previous public release
beta is for 5+ patrons, 70-90% of what was planned, 2 months after previous public release
final is free, 90-100% of the content + fixes, 3 months after previous public release
all dates are not final, delays are inevitable sometimes
basically alpha and beta get early access and get to see the content earlier
You can sub for month to access the version that you needed. More info on our patreon page.
