Hello,
Thank you for showing interest in our project! Yes, Erosion project is still being developed, you can check our Patreon page to see what’s new to the game, we are making the changelogs public :)
Indeed the updates come much slower to reach Public branch, yet on the Patreon we are more active.
If you would like to know what’s new being added to the game please take a look at our Patreon page once in a while. We are working on the last part of Build 0.1.6, after we finish the whole update we will post it publicly here on Itch too.
