I'm setting up a Patreon to fund my development.
I was thinking to provide anyone who is supporting me on Patreon with an early access version of the game. And as long as they support me there, they receive updates. If they purchase on itch, they just get a 1 time download, unless they pay again. (this is just my early access model)
Right now it seems that I can give my patrons access. But they gain access as soon as their cumulative donations reach a certain goal?
