I'm really sorry but I couldn't figure out how to open the game :( I tried running the server.exe but I think my antivirus killed it and localhost:5000 gives me a 404..

Sorry you had issue running. When I tested it after upload I removed the security block from zip file that gets put on downloaded files (Right Click file, Properties, Check Unblock at bottom)
I found that it works better to just run a python webserver from the publish/wwwroot folder
python -m http.server 5000
