If we would make game releases free we would bankrupt in few months with no more updates ever. We are using donations wisely to make more content, as we are small indie creators we want to be able create more content and early access is a small form of reward for people who are supporting us, it's only fair. We have no ads in the game and we eventually make every release free to public after some time. The supporters enable us to work on new content, take vote polls and we hear their feedback first hands. Keeping the project alive is time costly at the scale of supporting all platforms, even for a fan project. Please consider joining us on our SubscribeStar.
