Hey thanks for the feedback, you are right connecting through IP addresses is a hustle, unfortunately I can't afford a hosting or relay service right now, I would love to be able to add a server browser in the future
I tested multiplayer through LAN with my second computer, it could be some bug i missed, can you give some more details about the problem? Do you use direct LAN, Hamachi or Radmin?
Also you can dm me on Discord, my username: rapth
