I built my first portals yesterday putting the first one at my house in the starting area and then ran across the map to the shore side of the Black Forest. When I got there I sailed across to a Black Forest island I had seen in the distance, already been there and set up a camp, and decided I had had enough of running and sailing there.
I built my second portal and it would not connect. I sailed and ran back to make sure I had called them the same thing, though it wasn’t rocket science, I had named the first one BF but once I got home I realised I’d named the second one DF, as in Dark Forest. That was annoying.
Found the merchant, set up a second portal from home to him, and bought a fishing rod. Got to suss fishing out later. Also found 2 other biomes on this other island, mountain where I nearly froze to death, and then found a swamp where some leaches killed me and then a bloody archer skeleton did as well cause I want paying attention.
Great game.
