Did you try running the server and then connecting to it from your client? My main goal was to have it run on a dedicated pc at the end but I ran into issues with playing multiple games in a row that I was unable to do that. If you do run the server yourself you can port forward the port and have other join your game and you can play. Perhaps checking out the video as well.

Due to short timing on the game jam no AI was created for the project. You can try the test map by using the command "start test" on the server while in the game lobby

Sorry to hear about that! Got pinched for time and unfortunately could not run a server myself 24/7. You can play the game by downloading the dedicated server and running the bat file on the server. You should then be able to connect and try out the game.
