Dude if you paid 20$ before, you don't have to pay again. If you paid 10$ before, why would you get a version for 20$?
Because I don't have access to the current alpha version so I would need to buy it ($20) to get access. Not really sure what you're not getting.
Alpha usually wasn't even released here and on patreon it's always been 25$. It'll come down to 10$ soon, have some patience, we're still working on the update.
