codeisme i dont know what norway is, but you need to write code that will approximate player positions to account for the lag. this is what other games use and is called "prediction" code.. not sure how to implement but one way maybe this could give you ideas
I looked at that norway thing.. idk.. seems a bit too complex for a simple p2p.
The method i described was more like server browser, where you open up a browser and see what lobbies are online and join.. this needs the masterlist server that keeps all the online server in a list and when people open up browser they get served the list and then they can join any of the server using the godots enet multiplayer peer connections ..
