I played the demo! It's a really solid crafting-exploration game. I like the part with the boat.
Ah, bonus, if what I saw from a streamer is correct, your Demo save works in the EA full release. That may or may not always work though as updates etc drop. But maybe! Yeah the boat is really cool. Apparently there's a whole ton of hidden resource stashes in the starting area that you can clear out. Like insane amounts
(in the roof area above the boat hangar, then cut off the metal panels, and also some you can only access from the outside by jumping, etc etc)
