Are you going to bring the full version to itch? (please do, I love the game but my physical computer is too much of a potato to even install steam I have to use a VM which isn't super powerful)
I understand your concern, and it is possible that at some point we will, but not initially. Managing one store is already a lot of work, and the full version is also tightly integrated with Steam services; there is multiplayer and Steam workshop support that I would have to disable. Additionally, I'm not sure if your computer will handle the full version because it is a bit more demanding (CPU wise) than the current Itch version. After all, the world generation is much more advanced. To test it out, you can download the Steam demo in VM, copy the files to a physical computer and it should still open and let you try.
