Please note: all credit goes to Kunogi!

If your game open and stays on white screen and you using Windows 11

  • Go properties -> compatibility -> Use legacy display ICC colour management.

If you get the error (in korean) saying it could not connect to the server

  • Go to your firewall and add an rule allowing the game to connect or turn off the firewall.
  • For the firewall case make sure to make a custom Inbound Rule allowing TCP and UDP and also explicitly mark to Allow Edge Traversal traffic to come (unsolicited data packets from internet), otherwise the game wont work.
