itch.io

keep the server tool running (only for the person hosting... not everyone), the person hosting the game should put in their own ip and the others should put the person who is hosting's ip in the Direct connect option

not all the time..

some people have really bad computers and its not their fault and if the they really wanna play with friends its the only option

no, just port forwarding is needed and u need to set the player name in settings

ur gpu probably is the problem

it is because the mod version and game version are different, i think you could just download the same mod and it will work fine because the game mod comes with the game files instead of adding the mod files to the game files, plus, one person should start the game and the others should click direct connect with the hamachi ip address and port 50021 to join the lobby

yeah, but steam uses too much ram, i recommend using this with port forwarding, i love it, it works too
