You've washed ashore in a foreign land. With nothing to your name other than a few tools you’ll have to learn how to live off the land. Explore, grow crops, and...
And the Multiplayer as you saind its most difficult i kind of already figured it out cause so many great games dont have multi at the start, like Hydroneer an amazing game where the dev after years cand find a way to implement proper multiplayer.

Again thanks so much
